The unit is in and completed. Works great. The Old Air Products compressor mount is different than the one the VA. Since it was already installed the shop just ordered the interior parts, electronic controller, and electronic water by pass valve. The VA compressor mount is on the bottom where the generator was and drives off the crank only. The OAP drives off the water pump pulley. The power steering is now driven off the 3rd pulley which was already on my crank. It was just spaced forward.
I’m pleased with the performance so far. We shall see in the summer will bring.
