Hello there I'am working on a power steering conversion for my 58 truck. I got all the goodies, but have the steering box from a 1980 blazer 4x4. "how to" say's I need the 2 wheel drive steering box. Can anyone tell me the difference? So I wound get in trouble figuring out the steeringwheel turns etc. Any tips on "how to" are welcome. I had a lot off info from OrryG He worked with a steelplate on the chassis. And made it an all 4x4 conversion. Best truck I have ever seen!!! Thanks
