Im sure it can be done, but how much trouble is it?
Just exploring my options before the car goes off for some body work and paint soon...

I'd also like to match the trim on the car (so either all S4 or all S5 trim)...

 

about as hard as putting an s4 on an s4 because they are the same,its an easy 2 hour job because most of the time the bolts are rusted and hard to get off.....I would do it if i wasnt getting an aftermarket

 

I did it on my car. You cna't change the molding on the front end, because it is all one piece. The same is for the rear end on both series. So look into a s5 rear end also which is very easy to put on. Unless stuff is very rusted.

 

its not all that bad changing it..i put the front/rear and side moldings from the s5 on my 88. i think it looks sweet

 

how hard is it to find these parts for the s5? I would like to slap some on my 87 GXL. after i get them bad *** taillights too :P:

 

There are always people selling S5 parts on eBay and this forum.

 

Thats what i figured, just wanted to get some confirmation.
Thx guys.

 

I though you had to have the S5 fenders with the S5 frotn end...I put an 87 fender on my 89 and it never matched up good, wide gap on one side small one on the other
