There's no difference between V6 and V8 pedals. Might as well pick them up now while you have the chance and a source. Same goes for the interior shifter trim.
You need a flywheel, clutch, transmission, shifter, cable, and driveshaft. Might need a different crossmember as well, but I'm not 100% sure of that. Trans mount is specific for 96-98 cars with the T-45 as well, so you'll need one of those too.
I honestly don't know what would be needed when it comes to the wiring/ECU. You may need some kind of adapter for the speedometer, I don't know if the AOD uses the same type of sender that the T-45 does.
