The SN95 Mustang T5 (1994 and 1995 vintage) have a longer input shaft than the T5s in the Fox body cars. Therefore, the bellhousings are different. If you use the correct bell housing, it will work. There may be some other things that require changes, such as where the shifter comes up thru the floor, the length of the driveshaft for your application, etc. I'd suggest finding the right one for your application to save yourself headaches and issues.
