for the hydraulics you will need master, slave, pilot bearing, pedals, flywheel, clutch and pressure plate. For the tranny you will need bellhousing, tranny, shifter, torque arm mount and bushing, and cross member. Your a4 torque arm and driveshaft will work. I would also recommend getting new flywheel bolts and pressure plate bolts. Then there are the miscellaneous things like the upper console, shift boot, and electrical connectors for the tranny. You can make the connector for the reverse lights from parts you can buy at pep boys. All the other connectors are the same. I think that is about it.
