I have an 84 GT conv. that is completely rusted out at the fire wall and the floor boards. Not to mention the trunk area where the roof drains are, they are gone. I parted out the car and I am in the process of putting the complete intierior including the dash and trim on my 90 2.3L convertible. I have already put the front end sheet metal on it so it is now a 4 eye. I am not switching out the engine, although it would be a great thing to do, but the motor was a 92 5.0 and I put that in my 91 GT conv. already. I know this all sounds nuts, but I like the old Fox Body dashes instead of the plastic 87-93 dashes. I just need some help and advise on swapping the dash and harnesses over, wiring wise. Has anybody done this, please let me know.
