I know you would need a different bellhousing, and I would think a different shaft.
The 4.6 & 5.0 have different bolt patterns on the back of the block. The t-5 for the fox bodies & the 94-95 gt's are the same with the exception of the input shaft is about 5/8" longer due to the shifter placement on the 94-95's. The bell housing for a 94-95gt will be needed when using a 94-95gt & 94-04 v6 t-5. The 3.8 has it's own bell housing for the clearance of the 11" clutch. The 94-04 v6 t-5's are the same as the 94-95gt but the gear set is different in the v6 trans ( may be weaker ) Also the 99-04 v6 trans have a different speedo set up in the rear tail shaft for the newer cars but can be converted to be used in the older models. The 4.6's have the t-45's & 3650's. (96-04)
