You should be good to go. the computer will work fine on either engine. The intrument cluster should be plug and play also. Im pretty sure the tach wire is already pre-wired so it should work. The stick will go right behind the 91, just bolt on your clutch and flywheel and install a pilot bushing in the crank. Use the one that drives into the larger part of the crank and has the pilot bearing inside it. No crank drilling necessary.
