I dont know about fiberglass fenders,but the stock steel ones will fit,but the hood hinges are different and they have to be modified--havent done one in a long time,last one was a friends truck in the early 90's---sorry my brain cant recall all the details,but it wasnt a bolt on deal,it took some doing.Someone on here must know exactly what needs to be done! /forums/images/graemlins/blush.gif
