Forget it. If you look closely at the Mk7 r shifter it has a 'see through' silver section a bit like a golf tee holding the ball ( I guess that's what the designers were trying to achieve) this means the shifter onto your Gti / ed shaft sits about 30-40mm higher. The surround onto the fascia would also need swapped. Just go to VW and swallow some pain killers, then hand over credit card in tears as they stiff you almost £300 for a replacement knob.
