Here are some paint markings on the heads. I would assume this would have been found on f-85 and Cutlass engines also. I found it on all three of my Jetfire engines. The driver side is a mint color and the passenger side is a green.

Just found something interesting. The manual transmission Jetfire cars have a rubber plug in the air cleaner where the choke tube would go for an automatic car. These two plugs are both from known original 4 speed cars. The smaller one is from a 62 and the larger one is from a 63. Not sure if this is the standard between the two years but just found it interesting.

I never found one in my 62 4 speed car and I am sure it had never been apart before me. The back seat of our automatic 62 has never been out so not sure on that one.

These three parts tags are the only thing I found in our 4 speed car.

Would you be willing to scan it and post it? Would love to see what it looks like.

Radiator date codes

While finding the petcock and outlet difference above, I found the location of the radiator date codes. I figured they had a date code but never looked till now. The date code location is also different for 63 than what is on the 62 but not to far away from each other. It is located on the driver side tank and on the back (engine) side about half way down. The code runs from A to M with skipping the letter I. A would be January and B would be February and on to the end but skipping I. I looked at our 4 speed car and it was an F and the car was built in June so the date fits correct. It would obviously be possible to have a month earlier radiator in the car if the car was built early in the month.

These two radiators are date K and L.
