Quick difference between s5 gxl fender and s4 tii fender?
 

I need to know the difference between a front fender from a 91 s5 gxl and a 88 s4 tII. I have the s4 tii and it has a pretty beat up driver side front fender. Will there be any problems using the s5 fender? I'd be using my s4 moldings. Will that work on the s5 fender?

the stickers..... :p

I believe the location of the mounting holes are different between s4 and s5.

The moldings on a s5 and s4 are diffrent. so you might have to some how mount the molding using something else ( double-sided tape)..

Also i am not exactly positive, but the way the fenders connect to the front bumper cover differ from each series.

nope ive personally installed 3 s5 bumpers on s4 f's so if they bolted up different i'd know

ok, never mind the second half of my first post....haha

yeah, this is true. it works but it just doesnt look as perfect as the correct series fender.

The fenders are different from series. I sell body kits. Putting a S4 fender on a S5 you'll notice that there is a fender height difference between the door and the fender. A big gap. Bolting them on is the same. Molding of course is different.
