you need pedal cluster, gauge cluster, ecu, hydrolic brake mc res, clutch slave cyl, clutch/pp obviously, axles, center console forward section, shift cable box/cables, rear motor motor mount, drivers trans mount, and then you have the wiring, you can just jumper both clutch switches and the cruise/starter will work (cant remember if wiring is present, never taken apart a mk4 auto dash), and you need to over ride the starter interlock thingy for the auto gearbox.
Then you will have imobilizer problems, I recommend you purchase an imobilizer-defeated ecu at this time, infinite expensive headaches can be avoided.
but you will have an 11mm pump!
so, yes it can be done,
is it worth it?? eh, I would do it, but I wouldn't do it for anyone else. lol.well, maybe for a lot of money.
