Just did mine, I got the kit for the bottom of the gear stick from my local VW dealer! Cost ?12
Have a look in this forum there is a thread I started on the same thing, there is a link in there that someone kindly gave me, it's a step by step guide on how to fit!
You need two people and around 2-3 hours.
The pin on mine was a right git to get out, get some mole grips before you start to get the pin out if it is really stuck in!
The other kit I had a loacal mechanic fit for me, the kit replaced the lot by the gear box, and cost me ?100 fitted, the kit it self is around ?60 I think.
Good luck
