These were the wheels that were on my 1990 when I bought it, but I have no idea what they are? They look like possibly C-4 Grand Sport wheels? If so, can anyone tell if they are OEM or reproductions? They are 17”x9.5” ET56 and 17”x11” ET50. Hopefully someone can tell from the markings on the inside of the wheels.
Here are pictures of the inside of the rear wheel:
They're later 'reproductions' - even the early reproductions generally had the 'deep pocket' for 17 X 11 on the rears. They're nothing special and if you had them 'side by side' with original GM you could also see difference in the spoke fabrication.
If they are reproductions, where can I find another rear? Who sells them? One of mine is damaged and since they aren’t “real” GS wheels, I might as well keep them for my kart project and just replace the damaged one.

Wheel identification help needed.
