Anyone ever installed any? Wondering about their craftsmanship.......

I just did a set of Goodmarks on a 73 camaro. Hard to beat the fit. Needed very MINOR massage. They were my first attempt. Came out 100%. Even had 2 friends that were body men, give me complements.

I had the left and right quater panels Install on my chevelle with sail panel there are two type, one with the sail panel and without the sail panel, so I had little or no problem with then being install, and I bought them fron opgi, If I knew how to post pics I would show you, but I'm still learning the forum.
I have a 1967 chevelle ss.
