Soory to be a pain folks, but the US parts market is somewhat of a mystery to me. Where can I get the fabled 115a alternator that will substitute for the Urq's 90A unit, and how will I know it is the right one? I called a local Bosch dealer here in Ft. Lauderdale and the rocket scientist I talked to denied the existence of the TQC?? Any advice or guidance would be most appreciated. John C.
