I recently picked up 4 rally rims for my 68 Camaro, no tires, anyway they appear to have a 4" offset and I found the following markings: by valve stem YS also on the front K1 and under that a 9, opposite that a M. Can anyone tell me what they signify?

Thanks Steve

I don't know what vehicle "YS" is off from. This link will help with some decoding.

K19 means it's a 1969 wheel. The YS Code was used for Chevrolet rally wheels starting in 1969, and replaced the DC wheel (used from 67 to 69) as of 7/69.

Maybe those rims will fit a MUSTANG!!!!Are you sure you have a chevy and not a FORD

Mr Cool, good question nick
