1971 duster quarter skins

Hey guys! Anyone here have any insight on these skins? Is it pretty much a full quarter from the quarter window/body line down? What I mean is that are the mating areas in the door jam, tail light area wheel well, rocker and lower rear quarter the same as the full quarter or will I need to stitch weld all seams? I’m curious because I don’t need or want a full quarter.
