My Z10 has SS wheels and not Rally wheels, is that correct? I read they stopped making them around the first of 69, my car is a 05A build. The stamp by the valve stem reads:
M1 and has a 9 centered under them, 3, stem hole, 15, YA Not sure if they are right but the research on this great site did not have anything like the M1 with the 9 under it. Also did they start stamping the vin by the oil filter? Thanks for your help, I have found so much info on here its crazy. Kurt
