Could i put an 87/88 fiero formula front and rear bumper on my 84 se (without the facia and stuff)?
No matter which different "bumper" you swap onto an '84, there's going to some "stuff" required besides the nose itself. A base '87-'88/Formula nose swapped onto an '84 will at least require the specific egg-crate material and air dam. The plastic wheel well liners are also different dependent on which "bumpers" are installed. As mentioned previously by fierosound, it would be best if you were to remove everything you need yourself from a donor car.
The wheel well liners for the GT nose are different. Close to the same wheel liner as on the notch back but with a small added piece stapled in place on the front bottom. The small side trim piece is also different 86-88 but most of the time it stays on the facia when it is removed.
