Good point John, "Torque to stretch" type bolts must be replaced or they will fail if torqued a second time, but VW has used both types, identified by the length of the tread (stretch = 22 mm, std = 10mm). I would replace the stretch type with standard bolts if possible. Obviously both are dealer items and I am sure several $$$$ each times 8. By the time you replace these and the case studs you are in it $20O-$300 before even getting into the other major parts and machine shop work. Also, the Haynes manual states that the flywheel/drive plate bolts must also be replaced. Again, you get what you pay for, and a top quality rebuild will cost $3000 to $6000!
