I'm just in the process of blasting and painting my rims however, I noticed that the code is FW not YH. Is it possible to have FW rims on this car (Z/28 RS Mid May build date). I think FW is 1970 chevelle code but I'm not sure. If YH is the only code for that car what date should I be looking for so that everything matches. Thx Mike

FW is the '71-'77 code for the 15 x 7 rally wheel as used on A bodies. YH was used through the '70 model year on Monte Carlos. The wheels are dimensionally identical. A good date range for your car would be K194x to K195x.
