Plastic Parts Made for Ferrari and Lamborghini

There were few replacement parts made for Ferrari and other Italian cars because the production numbers were so minimal and any stock was exhausted long ago. Many of the mechanical components for Ferrari’s are common to most models but the body and trim parts are getting hard to find.

I have taken it upon myself to make some parts. Long ago I made Air Conditioning vents, knobs, and little parts for 330GTC/GTS’s and 365′s. Every 330/365 at our shop is missing the alternator junction block cover and knob so I have re-made these parts. Often, the junction block itself is melted from years of engine bay heat and electrical heat so I make the complete units too.

Awhile ago, I made the thumb screws for Lamborghini air cleaner lids with the FIAMM logo.

Now, I am working on making some shift knobs, interior knobs and trying to make the vent window knob for the 330GTC so let me know if you need any of these parts.

If you need a part made, please let me know. Its easier to make a copy from an original part but I can make a part from a mechanical drawing as well. I am learning the techniques to make the molds, hard point holders and account for the shrinkage of the liquid plastic as it sets up.

Here are some of the parts I am making so far.

Very Orignal Ferrari 330GT 2+2

If you ask someone who remembers owning or servicing Ferrari’s back in the 1950′s or 1960′s, they will probably tell you that they weren’t very well finished. My father often says that we make the cars significantly better than they were when new. Judges on the show field have been known to deduct points for a car that is “over-restored” which must be a very hard thing to determine.

Most Ferrari’s from the 50′s and 60′s have Borrani wire wheels. How brightly they are polished seems like a bit of a sliding scale. If you spend $5000 to have your wheels rebuilt, don’t you want them to be highly polished? I have seen many photos of a Ferrari chassis rolling on Borrani wheels while the body is being constructed at a coach builders shop so there is no way the wheels were shiny after that gritty process. I would guess that Borrani used more of an industrial chrome plating on the spokes and hubs and lightly polished the alloy rim but you wouldn’t need sunglasses to look at them!

Another example is the satin black paint on the chassis and engine bay. From what I have seen, it appeared to have been hastily applied by brush right over dirt and weld spatter. I’ve always tried tried to imagine how the rubberized undercoating was applied and picture someone holding up cardboard to prevent over-spray while blowing it on in heavy coats.

Pininfarina used some different practices than Scaglietti but overall, I think there was lots of similarity. Pininfarina used super heavy rubberized undercoating that looked like sagging elephant skin. Scaglietti used a lighter coat of “pebbly” rubberized undercoat.

Anyhow, we had a incredibly orignal 1964 Ferrari 330GT 2+2 in the shop last month. This car has 3000 miles and was perfectly preserved in a dry climate so you can see all the evidence of the original build practices. In the next few blog posts, I will show some of the intricate details on how this car was finished 50 years ago. If you are interested in getting a flash drive of all the details of this car, let me know.

Here, you can see the thick “elephant skin” undercoating and other details like black oxide radius arm bolts. You can see lots of gold over-spray on the thick undercoating. This may mean the car was painted after the undercoating or the car was touch up after it was assembled. There are many other areas of touched up paint on the car.

Note the think Dijon mustard colored paint on the bottom of the cross member but the thick dripping black paint on the radiator support. The Chassis does not appear to have been painted like many restored cars. It is more a blend of over spray and rubberized undercoating. Note how sloppily the yellow tamper evident paint was applied!

Ferrari Steering Gearboxes

Earlier this year, a good customer drove to the shop in his 1967 Ferrari 330GTC for some service work and asked me to critique the way his car handles. We went for a spin and I immediately understood what he was talking about, when entering a curve it took lots of “input” in order navigate a corner and even go straight down the road. I use the word “navigate” because it handles like a boat.

We have had the suspension aligned and he had it aligned at his local shop a few times in an attempt to remedy this problem but it still steers super slowl. We compared it to a few other cars that day which validated our feelings, there was something wrong with his car.

Ferrari used ZF steering boxes in all of the cars from the mid 50′s through to the Daytona in the early 70′s.  A 1:20 ratio was chosen for the 330GTC but the 275GTB of the same year used a faster 1:17 ratio. My solution was to buy a brand new 1:17 worm gear to replace the 1:20 and see how it goes down the road.

The handling was transformed and it finally felt like a sports car. The 1:17 ratio was the perfect match for the car, even the steering effort at parking speed wasn’t compromised. I really don’t understand why the 330 got the slower steering but I have since changed the ratio in three other GTC’s. If you have a 330GTC or even a 330 GT 2+2, you’ve got to install this faster ratio steering box, you will love the transformation

Ferrari 330 and 365 A/C Vents

Ferrari 330/365 A/C Vent

Ferrari Air Conditioning

Awhile back I published a post on reproducing the often broken or missing vents and knobs for the Ferrari 330 and 365′s that showed the  prototype to review before the final production. The final order of vents have arrived in a box and I challenged myself to make the delicate and finely detailed knobs that go in the middle of them.

Late production 330 GT 2+2′s had optional Air Conditioning with 3 louvered vents in the middle of the dash with little thimble sized knobs that you twist to both direct the air flow and operate the fan speed and temperature of the A/C system. The middle vent had a blank knob and the outer vents said “aria” I II III (for the three speed fan motor) and the other outer vent had a knob that had the script “freddo” that controls the temperature of the air outlet. I found some very good original knobs and cleaned them up, chipped the white paint out of the script and sanded the delicate fluted lines on them to make a good mold. Then I made tooling to make consistent parts time after time to fit the “D” shaped switch shafts. The results are amazing, I am so impressed at how great everything came out.

I didn’t make the louvered vents, these parts were extremely complicated because the outer cylinder of the vent is on a different angle than the louvered slats, how do you make a mold that not only pulls apart straight but allows the louvers to be on a 45 degree angle! Since I paid the big bucks, I own the multiple piece mold and may tell you the secret someday.

The only part I have not made are the chrome trim rings that go on the outer edge of the vent. Later this month the tooling will be finished up to stamp them out of brass and have them chrome plated to match the rest of these lovely little parts.

In this photo you can see the simple little tool to make the fluted knobs. I can only make one at a time but the same tool makes the “Aria”, the “Freddo” and the blank knob. Since I am using the slow cure plastic, I can only make two knobs per day but will experiment with faster cure resins to churn them out a little more rapidly. (if anyone actually orders them)

Antifreeze Doesn’t Last Forever

What makes antifreeze go from alkaline to acidic? Does combustion gas leak from the head gasket and contaminate it or is it the heating and cooling process? Regardless, we have had two corrosion situations from acidic coolant recently, a pair of 330 cylinder heads and the core plugs in a 365 GTB/4 Daytona. To be fair, the core plugs are very soft alloy in comparison to the engine block so they are kind of sacrificial, unfortunately they are difficult to change. These plugs were so delicate that just by scraping the crusty coolant off to find the source of the leak, the screwdriver poked right through them like they were made from waxed paper.

The 330 heads are a combination of a bad casting and corrosive coolant. I saw a youtube video showing the process of building a modern Ferrari 612 engine where an MRI test was used to determine the thickness and integrity of a cylinder head casting. They didn’t have this technology in 1966 and this is the evidence of it! The deep pores in the exhaust port aren’t from corrosive coolant, it’s from a horrible casting. The pitted areas around the water passages are due to corrosive coolant rotting the material away.

Welding holes in Ferrari 330 V-12

Like a dentist, I drilled and scraped the corrosive material out so I could weld the holes that were leaking coolant into the exhaust and intake ports. I don’t often remove valve seats and realize what a difficult job it is but I found a great way to get them out easily. I take a valve with the same size stem as the original (8mm for Ferrari) but has a slightly smaller head. I weld the head to the seat and drive the valve and seat out with a hammer from the back side!

Anyhow, after welding, grinding, pressure testing a number times, I finally have the heads sealed up and looking great. After grinding and cutting the core plugs out of the Daytona block, we installed the new ones and sent the car home.

Altered photo of Ferraris

I’m not feeling too inspired to write on the blog but thought I’d try to make a photo look like it was taken years ago. Not that successful. These are two cars that I really like, the convertible is an outstanding original example of a Pininfarina Cabriolet and the other car is Ian’s 330 2+2 that we just finished re-upholstering.

1966 Ferrari 330 GT

Grigio Notte Ferrari

Ferrari Grigio Notte

Earlier this week I visited the passionate owner of this extremely nice 1966 Ferrari 330 GT 2+2 in its original color called Grigio Notte. Typical of Italian Style and complexity, Grigio Notte (dark silver) has a tiny drop of green mixed in to give it that exotic hue unlike “grey” colors that you see on other cars.

The owner picked me up at the airport and we drove the spirited car about 25 miles to a friends shop and then to his house to check out all the other parts and documentation he has acquired with the car over the last few years. After all this we went to an outstanding BBQ joint where Nachos were based on thick cut potato chips with beef brisket and the shrimp sandwich was out of this world.

I was blown away at how well the Ferrari drove with a very strong engine, smooth drive shaft and all electrical components working as they are intended. Equally amazing was the ownership history and service documentation that the owner pulled together as well as the often missing handbooks and pouch to make this a very complete and sorted car.

The Interior is Finished

And it looks outstanding. We haven’t installed the front seats because we are working on a better set of seat belts but check in later for photos of the complete interior. The headliner looks amazing too, but Jim cursed the project because the material is much thicker and extremely difficult to work with, you’d never know by looking at the arrow straight pleats and detailing

I just don’t get it

This is a subject that I write about frequently because I just don’t understand why Ferrari Transmissions are bigger than the engine in front of it. We just had a transmission out of a 1955 Ford Pickup that was the size of a shoe box and a 5 speed ZF transmission out of a Maserati is tiny compared to the 5 speed out of this 330 GT 2+2. If I seem frustrated it’s because getting this Parthenon out of the car is a job that only Zeus can handle.

This transmission works well but the synchronizers are worn to to point of having a chrome plated polished look instead of the required rough cast finish but all the bearings and gears are perfect. We used to replace the operating sleeves on these transmissions but they take so long to “wear in” that I feel they are doing more damage than good especially considering how well they shift with the original parts re-installed.
