1970-1973 Z-28 wheels/71-72 Chevelle SS wheels?

MY70SS396 · #1 03-28-2008, 07:40 AM

I just bought 4 wheels, and yes they have the right valve stem hole. How can I tell what they were on and what year? I'm used to 69-70 Chevelle SS wheels. Any help would be appreciated.
Thanks,
Mitchell

let's see if I learned my NastyZ28.com lesson... The hole for the value step will say "AU" and will be a round circle not an oval shaped, egg, "hole." Originals are rather tough to come by but "aftermarket" or should I say later editions are similar/incorrect but good for driver wheels/tires.

Good luck,
Dan

Did I get it right 2nd Gen Camaro guys?

I am not sure I understood what you said. So I will take a shot at it: early 1970 wheels have a 1 by 5/8 oval valve stem hole, all others up to and including 1974 have a 1 by 13/16 oval hole and 1977 and up have a round hole.

Late 70-74

77 and up

Sorry, I don't have a early 70 wheel to show you.

My mistake, I said the valve step hole information backwards... was a long day. Sorry for the confusion. Thats what I get for being removed from the second gen community.
