Re: 8.1L and 4L85e swap into a 1972 Custom Camper 4WD

Power steering - the truck is a factory air original so it is important to make it work with the new motor. Taking Dirty Larry's advice, I installed the accessory brackets on the front of engine from a 2004 Topkick 4500. That also requires switching to the water pump, harmonic balancer, tensioner, A/C compressor and power steering pump from the Topkick. So far, I have found everything but the power steering pump.
I have a brand new power steering pump for a topkick hahaha
