Yep. It will be a direct bolt in. You will need to replace trans w/ 2wd trans and get the drive shaft while your at it. Be sure you get the same wheel base or you may find yourself looking for the right driveshaft.

motors are the same but there on differant sides the left to a 84-88 will fit the right to a 90-96 and the right to a 84-88 will fit the left of a 90-96

Depends on engine, transmission, gearing, etc.
my uncles 84 fiero only opens with keys. My Fiero has a button on the top right of the gauge cluster that will open the trunk. It has to have a battery or the engine running to do so though.
Auto, or 5 speed ?
