The problem with some garages that have done 'loads of T5/6's' is that they've done loads wrongly, I can reel off several well known converters and garages close to me that claim to know all about VW vans. In reality they are all crap and that's why I have to take mine on a 3 hour round trip to get the work done properly.
Where in the country are you, let's see if we can point you to a decent garage that actually know how to use their wheel alignment kit.
