if your using the 90 GT as a donor car your going to have fun. If your wanting to keep A/C you might as well swap the accessories and everything on the front to 94-95 setup.
Now if your patient enough. You'll still need to swap to at least 94-95 Harnesses. I Have a gentlemen bringing me a 94-95 V6 mustang and doing the same swap you are and i'm going to cnovert his 94-95 Harnesses so all the plugs and connectors are in the correct spot for the Fox body setup.
Yea I would be using the 90 GT as the donor. I want to know what all would need to be done to the 95 stang. what I would have to swap out to make it work? would it need a new rearend, new sending units just everything that would need to be done?
Complete drivetrain (motor/clutch/tranny/driveshaft/rearend), all electrical engine management, exhaust. I haven't done the swap so I don't know everything, but that's a start.

Rollin5.0 is correct... But when it comes to electrical the Fox wiring your going to have to splice about every wire when it comes to were the wiring comes into the car. Thats why I'm doing this gentlemens car with 94-95 Harnesses so its a no splicing deal. Just have to move some connectors thats all. But he's going to run a 94-95 T4M0 also.
Now GTwannaB if you changed just to the 94-95 Engine bay harnesses and computer and do what I'm doing for the Gentlemen in Michigan the swap is very easy and cheap.
