    This 71 has a manual steering. It looks like the holes line up but will a powersteering box off a gen2 chevy bolt to the frame ok? If so I'll throw a PS pump on it and make life happy. :D

    Yes, any power steering gear box up to 1980 1st design will work for your year, since you need a gear box and a pump you can use the later ones as well but 1980 2nd design and later used the metric pump with the O-ring lines instead of the flare fitting lines. The only exception is you may need to change the rag joint to the proper one to mate your steering shaft back to the box. GM used two different size input shafts which each requires the respective rag joint to work.

    as long as they match should work o-ring or flare. I took my box and engine and everything from one truck to this one
