a few q's and thoughts

I just picked up a 1975 firebird at a police auction. the car has seen better days, interior is completely shot, maybe 20% of all the seat covers is still present, the rest is all the foam, it has minor (relatively) damage to the right front fender and the plastic front nose piece. I got her for a measly 350 bux ! :D
anyways, I soooo drool over the 1974 formula front end appearance... is this an easy conversion (swap fenders and nose piece) and is this considered a no-no? I am also looking for "cheap" sources for parts (seats or uplostering) body parts, mechanicals etc... any suggestions?

as far as the interior i can't help you but as far as the mechanics gooes the early firebirds are really easy to work on i would suguest a haynes manual and a new set of tools
