so if steel fenders are removed, unbolted, spot welds drilled out, fiberglass just bolts on as the propaganda says?? no bonding or such? just bolt on?

fiberglass doors just bolt on using factory hinges, latches, bla, bla?? what about windows? I have seen where you can use factory regulators or others just use pins and lexan. can you get the lexan windows premade or do you make your own??

just some general questions while I decide what I may want to do.
