Welcome to PF dude
If you can't find the info you need about the old rst on here, then I will be very suprised. Just a word of warning though, be prepared to look at LOADS before you buy one as most are just tarted up rot IMO. There seem to be quite a few nice ones popping up in the for sale section on here, which seem excellent value for money with all the work that has been carried out.
I love a good VAG, get some pics up of your own
