im noticing that there might be a diffence in the way the hood lines up, my mail concern is will the front bumper of a 91-92 fit an 84 trans am?

 

The hood will fit fine, but you will need the following. Impact bar, absorber, head light assemblies, bumper cover, upper and side mounting brackets, marking lights with wiring, grill inserts...I just got all those parts together being I'm going with a 91-92 Formula nose. All the parts used cost me $1000, prob another $700 for paint and install.

 

The guy above me forgot to mention that the motors on the headlight buckets WILL NOT be a direct drop-in as yours have the 3 wire motors and the later models have 2-wire motors. Not sure how to rectify this, exactly, as I don't have an 84 or FSM for that year. You may end up getting a lighting harness for the front end of your car.

Also, I noticed one thing when I did my swap with a passenger's side fender from an 84... The fender to bumper joint may not line up properly at the top and leave a gap. This was a fender from a stock 84 that fit fine, and a bumper from a 91 with no damage other than a couple missing brackets (that have been replaced) and scuffed paint.

 

I'm hoping my 89 head light motors will work, I've been told they will?

edit...87-92 headlights are the same

 

May I ask why? Do you just want the look, or is your current nose damaged?

Based off what TPI-Formula350- said, you could probably buy a whole car for 1700.

 

I'm doing it for the look. $1700, is just a drop in the bucket as far as what I've put into the car in the 17 years I've had it
