My quarters are O.E.R. (Original Equipment Reproduction). O.E.R. is licensed by GM as an official GM restoration parts manufacturer. Although they come with a disclaimer stating that minor dings are considered normal because of shipping, I don't have a scratch or ding in either one. I've been impressed with the fit so far. We'll see when I actually put them together how well they really fit, but I think they will be fine. I set them in place and the measurements from the old body match perfectly to the new quarters. Sure beats paying upwards of $1,300.00 per, for N.O.S.
