I took my suburban to the paint shop for an estimate a couple of days ago.The body man suggested that I replace as many body parts as possible with aftermarket parts,fenders hood etc.My question is are they any good? are some better than others and what should I look for as far as the best quality.Are they better than using solid originals. I went to alot of trouble to purchase this virtually rust free truck from Albaquerque, completely solid except for a small hole behind the left rear tire.Of course the desert heat as burned alot of the paint off and there is surface rust but the parts are really solid.What to do?it always seems thet the members of this board are looking for solid original parts to use. Why?
