I really need to find a fender that will fit a 91 gta front left hand side. All the ones I find are only for 85-90 or don't fit gta. Anyone know where to get one?

Any fender from 82-92 will fit. GTA's did not have fender vents, but did have ground effects, so obviously get one without a fender vent. You can get a fender without any GFX holes in it, and drill your own. It really isn't hard, I have done it before. Ones for 82-84, and 85-90 GFX cars will have holes drilled for their GFX, and you'll still have to drill your own.

Go look in the classifieds section.

Your best bet is going to be finding a used one of a 1991-92 base model Firebird. Most of those cars came with the W68 Sport Appearance Package, which included the same ground effects that were standard on the T/A and GTA. PLENTY of those cars in the yards around here. Depending on what color (and condition) your car is, you might even get away without painting if you can find the right used one.
