ive got them on my 94. fiberglass quality seems pretty stout, no cracks yet and ive been through so heavy brush with it. i do have to say the fit is pretty crappy though. for $350 the lines for the hood are out about 1/4in front to back, which is due to one of the fenders is almost 1/2in longer than the other. where it meets the A piller, none of the lines even come close, have a huge gap between cowl and fender by the a piller. door jams are way off and both fenders bulge out a 1/4in or so past the doors around the middle of the fender.
if i had to do it again i wouldnt waste my money on baja fenders from them. not sure if the ones from rustys are any better but after a week worth of fitting mine up they still look like shit up close. just too lazy to change them back.
