BKarol

I posted this in C3 and did not receive a response "Is there any way to determine if a wheel is original ? The wheel in question was removed from a 75 Corvette. Brushed, has the ring, etc. and also has the letter "C" stamped on the grip. I have seen them on ebay stamped "B" and "D" & they claimed them to be original. What do these letters mean?"

Friend has an original 70 and the letter D is stamped and a 73 which has a K stamped.

Can't seem to find the answer anywhere and the judging manual does not address this stamp. I am guessing month but don't know for sure.

Thanks.
