Are 87to 90 T/A fenders the same higght as base Firebird ones?
I like the side vents but don't want the ground effects. Also what is the best way to file in the GFX holes besides welding??

 

Help anyone?

 

Thair all the same exsept the vent holes most after market fenders dont come with the holes for the ground efect you have to drill them your self.

 

Thanks. So the only thing that is diff. is the placment of the air vent.

 

The air extractors (vents) are in the same place, just the size of the actual extractors are different. 82-84 have one size and 85-90 have a different size. 91-92 TA's have no extractors. The differences are slight. All 82-92 fenders are interchangeable (they will bolt right up) the differences are in the drillings for the gfx.
If you don't want to weld and grind (which is the proper way), you can put a fiberglass patch behind the hole (to act as a backing)and fill with bondo, but over time the bondo may pop out. I say may because I used this method and have not had a problem in three years, but if yours pops out, don't say I didn't warn you.
