Below are pics of 1st design and 2nd design lug nuts. I believe 74Z28 still had 1st design.
Not sure when change over occurred. Many owners back in the day must have bought new lugs over the counter as OEM/Assy line lugs got abused.
Vast majority of owners dont know the difference. Camaro Nationals 2nd Gen Judging is ONLY show I know of where these would be judged or looked at.
2nd Gen Z28 trim ring lesson pics while I was taking pics from my Photobucket
AMES Pontiac parts site sells a repro of the 2nd design that is very acceptable and affordable for all but the most
fussy owners........I've never been told why AMES didnt reproduce the very hard to find FIRST DESIGN
