OK, heres one for you restoration guys... I have always thought that the original SS center caps were always "deeper" dish (the part where the SS sticker goes) than newer GM pieces. However, I have recently found some caps that are the shallower variety on a very original, seemingly unrestored, set of wheels, complete with pits and faded decals that are the shallow variety. Are both correct? Was the deep offset for 70 and the shallow for 69, or vice versa? Was it just 2 separate manufacturers originally? or was my original assumption that only the deeper ones are originals, and the set of shaloow ones i just found really over the counter, later produced pieces that are just prematurely aged? Does anyone know what i'm talking about?
