My friend recently bought a 73 454 T top car that has those wheels on it. I told him I thought the car was supposed to have rallye wheels on it,I had no idea that those wheels came on 73 Corvettes. Are there date codes or anything to prove they are 73 wheels?

I'm not sure if they have a date stamp or not. There where only 4 cars that where ordered in 1973 that had the YJ8 wheels. GM pulled them because of porosity issues in the metal. The ones that came with mine I believe were off of a 1980 car. They have subtle differences in appearance between the years.

They are not easy to work on that's for sure. I'm contemplating doing the same, pick up an old Chevelle or something. I used to have a 67 Chevelle and a 64 SS Malibu. The one thing that made this 1973 C3 build easier was pulling the body and building the entire chasis at work on my spare time. I completely stripped the frame had it bead blasted, painted and then reassembled everything with new rubber, front end and rear end components, brake and fuel lines etc. I dropped the Muncie and engine in it and replaced all the u joints, dropped the radiator in it, pointed a shop fan at it and broke the new cam in with the body off. Once that body is back on it's a pain in the butt to work on.

There were no YJ8 wheels in 1980. The option code changed to N90, and the center was no longer black.
If they look good on your car, and hold air, run 'em!
