The DSG quaife diff comes with ARP crown bolts included, but is around £200 more than the manual.
The manual diff bolt kit (02M/02Q) is £124.37+VAT = £146.13 (at 2009 price list I have in front of me)
May be worthwhile asking for a discount on the bolt kits too
Also it may be a good idea to see if fitting prices are different for DSG
