Help! Can anyone with a Bentley for the Audi 80 (I think the same book covers '88-'90 Audi 80, 80 Quattro, 90, 90 Quattro) tell me if the harmonic balancer tools needed are the 2079 and the 2084??? I'm trying to make a purchasing decision, but need some helpfull insight first!!! Many advance thanks!!! -Mike 87 5000CS TQ
