The Trans mount hangars have changed from the FOX mustangs to the 94+ cars. The Fox mustang had a hangar that side in from front to back, where the 94+ has them going in from outboard to inboard. That is really the only difference that I noted. If you don’t mind doing some welding or changing the hangars on the car, you should have no problems getting them to fit.
Those mountings should be the same, I dont know if there is any difference in pipe diameter, and make sure its not a cobra cat back from a cobra with an IRS... it wont fit over the solid axle.
