And one other thing that all I have is here say information on.... this old guy at salvage yard told me these older trucks had a few different options s for steering: manual steering, power steering, and assisted power steering... he explained to me the differance between p.s. and a.p.s. is the a.p.s. has a hydraulic cylinder plumbed from p.s. gear box which helps move wheels easily when stopped and the regular p.s you just by pass(loop the lower fittings on p.s. gear box)cylinder option. And instead of just looping it I was gonna add a p.s inline cooling condenser to keep fluid cool. Does this sound right?
