Quarter panels
The 72-73 Duster full quarter replacement panels from AMD also have issues with the fuel cap depth. I ended up installing a 72 fuel neck tube and 72 cap on this Demon and installing the 70-71 marker indent frames. AMD are not perfect but with the correct tools and knowledge you can get them in place.
These quarters you questioned about fit over the original quarter , I have a set here. So if you hold them on your car centered in the wheel house they extend past the door and beyond the end of the quarter in the rear. Also they do not have the bumper indent as seen in the picture. Also the gas cap hole depth is incorrect. Just a warning. They should be used as a patch not a full quarter replacement.
