94-97 V6 mustang T-5 work and are somewhat easy to find. These are exactly the same as the later foxbody T-5. You have to use your 95 bell housing.
The problem is the input shaft on your 95 T-5 is different. They are specific to 94-95 only. Your best option is to order a rebuild kit and rebuild your T-5. They are easy to rebuild and tons of info on how-to is available. If you must change the trans, the other option is to find a 5.0 bell housing from a foxbody and the 94-97 T-5. It will push the shifter back a little.
