I finally took my formula wheel off and am taken a close look at it. As far as I know it's original to car,we have owned it since 76. I dought it has ever been changed it had a vinyl wrap and hope it can be fixed and made round again. But I don't have an ic stamp. Is it possible they didn't engrave it? Is there a physical difference between the ic and 73 blank or did they run a blank.through 73? There is possible factory errors and that original wore out early in life . I simply don't know. I do own an ic wheel and a good driver original blank.so im.puzzled my this wheel.
