throttle cable bracket (maybe, don't know the GT setup)
forward fuel lines (from filter to rails)
EGR tube (don't have a clue if the GT one will work or not)
intake tube from MAF to TB
Other than that, you will have to do some wiring/pigtail changes and cut the end off the cruise cable and maybe do some bracket mods for it also. Not sure if you would have to do anything with the coolant line under the intake. Pretty sure the GT fuel rails and FPR would work. Going with the plastic NPI intake would gain some power and the fuel and throttle mods would then be ready for a PI swap.
Cheapest and easiest would be to do like 95 DD said and to swap over your 95 intake. If you go this route, while you have the intake off, I would highly recommend cleaning all the EGR passages, valve and anything else that's a pain to do with that intake on the car.
