Someone told me that all the parts do interchange, but I think that my 90 GXL(I think) vert looks a little different from the 88 GTU that I used to have. I need a new left front fender and a front bumper cover. If they do interchange, I can get the parts pretty cheap. What do you guys think? Also how difficult is the job?

 

those parts you mentioned are interchangeable. the molding style is the only major difference.
