I need to replace a fender on my 92 fox (GT). I am going to grab a used one from another board I frequent. But I want to make sure that I am getting the right one. From what I understand Ford changed fender size slightly in 1990 to allow for the new 16in pony wheel. Is this true? If so how can I make sure I am getting the proper fender without trial and error? Are there some markings or somethign I can look for? Please Help.
