Please note there are two kits from GSF both good value, one is just bushes the other has the lower part of the inside the car gear lever parts, but I found out this weekend that if you replace the lower part of your gear lever inside the car, that the spring in the GSF kit is too short and thus allows you to push down the gear level too much and doesn't allow you to slot into reverse properly, so be warned, everything else in the kit is correct. Sometimes buying from VW themselves will be cheaper than GSF, I managed to get a replacement spring from VW for 60p - bargain
The link above is very useful.
