Is there a way to tell if replacement doors are factory GM, NOS, or other when the origin is unknown?

thickness for sure,tap a real one,then a repop
most factory drivers doors have stickers new
fit and finishing tells too

They weigh more! (its easier to tell if its just a shell) That is how I tell, especially if they have been painted and the stickers have been removed. Also if they are mounted on the cab, aftermarket doors usually require spacers between the door and the hinges to fit correctly.

and like motornut said, tap on them if the sound cheap they probably are.

Don't think these are GM or NOS........my rusted out doors don't have waves like that.

Thoughts?
