I am replacing the small lower rear quarter patches on both sides of my 69 2 Door and have done many searches and found little to nothing on who has the best patch pannels. HELP!

Go with the US made stampings if possible. NPD carries them.

woooaa there i got a back right floor pan for my 67 from NPD and the panel has two cut outs in the corners where the floor pan transitions from floor up to the back seat pan. its hard to explain but the panel is not continuous ther are slits where there should be a curve in the corners. i would say if Good mark has it get it. other panle that i have bought from year one have been thinner than stock which kinda pisses me off to.

Yep, i had a rear pan like that to.Its actaully easier to form the corner the way you want to with the slit than it is reworking a badly stamped corner. Goodmark patch panels are mostly made overseas. The US panels are thicker and a crisper stamping.Usually if it has black primer(EP) its overseas,if its bare metal its US. I bought some floor pans for my chevelle from NPD and they were nice, thick US stampings,made by American Designers,(or something like that) Sherman also sells mostly US stampings.
