64_c10,
here are a couple pics of the power steering unit before i installed it onto my truck. Its pretty basic the way it bolts to the motor, two spots on the head, then a supporting brace that shares the tension adjusting bolt of the alternator.....
I got this power steering setup off of a 62 chevy II that had a 230 in it. My truck has the 250, which shares the same head as the 230 so it was a perfect fit.
