You need Mk3 outer CV joints and 5 stud hub + MK2 bearing carrier with either B3 Passat/VR6 280mm discs.
The bearing carrier needs to be pressed out and pressed in.
To get camber and castor right you might need to adjust the ball joint fixing holes, cant remember exactly...
Rear beam just bolts up but you need to fiddle with the bias valve iirc.
Do a search under Mk2/Mk3 4 to 5 stud conversion, been done a lot of times
