Buy a remanufactured gear box. Its not that pricey and you know what you got. I did buy a Kit from a vendor. The steering arm, and adjustable drag link, and a couple bushings/nuts and bolts were very good quality but at 100 bucks I thought still a little pricey.

You can read a couple of good articles about converting your truck to power steering. There is one at this link below but I lost the link to the other one.

I'd rather walk and carry a Chevy hub cap than ride in a Ferd.
I can explain it to you, but I can't understand it for you smile
