The T-5 from an 85-95 can physically bolt up. You'd have to swap the flywheel (50oz.), bellhousing (1985-1993 are different from 94-95; 94-95 T-5s have a longer input shaft), clutch set, and you'll have to adapt a clutch cable to the pedal. Another issue is with the programming of the V-8 EEC-V. They are set to work with the automatic. I don't know how to explain it, but the D.I.S. (distributorless ignition system) plays a part in how the engine runs if not used with the correct transmission the EEC-V is programmed for.
You'd need the entire donor vehicle to do the swap. It will be much more difficult hunting down part by part.
