MRGTX Well unfortunately at this point it sounds like the "shop" just destroyed my TRW Pump.
The reason it is so hard for me at least is that the TRW had 2 different sizes. Large and small then the federal had a different shaft also. Then there were different setups for AC or no AC on each with different diameter pulleys and different offsets from the pump. From what I have gathered there are about 8 different pulleys that are possible.
