Does anyone have experience with the newer PS pumps with the remote reservoirs? I see that dirt track racers use them alot with custom brackets. Do these things work with PS gearboxes found in Chevelles, or are they for racks only?

Yes, the Type 2 pumps do work with conventional boxes. I have one on my Chevelle and Sherri has one on her 59 Biscayne. I know one other Chevelle that has one. They work fine. Alan Grove sells a bracket kit to mount the pump.
