already done it mate
i have a 2.0 na, used the 1.6 fwd gearbox using the 1.6 fly, the 1.6 clutch, and the 1.6 shafts which fit directly in the 2.0 hubs...removed all the other stuff, prop, rear shafts and diff....released the outer c.v's from the shafts, cleaned up and fitted in rear hubs to hold bearings together.
