Im a body man and i to hate aftermarket parts i have installed alot of them and mostley keystone but i have
had to send them back and get another set of doors to get them to fit and still had to bend top and egg hinge holes out to fit the same whith fenders and i would not even mess whith the hoods i have had pretty good luck
whith the patch panels except for door skins there not curved right another advice glue them in rockers and cab corners if you weld them they wont last because of the heat . my self i would rather go used thats what i did on my 84 chevy,i would rather fix a a big dent than
put up whith after market another tip i bought a pair of
used chevy doors and i sand blasted the inside on the bottom near the pinchweld and used por15 on them i did the same when i put my patchpanels in that was a tip i got from a freind that restores antique cars.
