Are there any known differences in gm inners compared to reproduction ones?
If you're looking at unknowns, used originals have staple holes. Repops don't. NOS don't have staple holes either from what I've heard. I heard repops are thinner & might not have dimples. Don't know if that helps. I bought used wells for my car...Joe
I thought I found a set to have on hand and the lady had no idea what she had. Now she says they are for the rear fender. Clueless lol
