AMD 70 Road Runner rear quarters - opinion?

Has anyone had first hand experience of these panels? Not only the fit, but the shape of the side scoops? I have a pair of full cut off quarters, but they are quite wavy, and since it's a black car I am considering that new panels may save a great deal of time
in prep. Thank you in advance

Either way, you will have a lot of fitting and block sanding to do in your future. If it were me and what I had on hand was decent and rust free I would use them. I don't have any experience with your exact panels mentioned, but I have done a lot of paint and body work.

I have install 3 set the first set was when they were just introduced had some small fitment issues. #2 set fit much better #3 as well
I'm waiting for a set now one of them is back order now
and yes you will need to block sand being a black

Find a body panel expert and have that person evaluate the cutoff quarters. If you can use original, you’re much better off.
