Power Steering

[GlennBrittain]

This may be old news , if not maybe this will save some the problem I had. I replaced the power steering gear box on my 69 C10 with a rebuilt unit from my local NAPA parts store. Of course I took the old one in for exchange. After I bolted up the new one, I discovered my steering shaft coupler would not fit my new gear box shaft.
I purchased a 68 thru 76 gear box, this one has a 13/16" shaft, I discoverd my coupler was for a 77 thru 86 power steering gear box which is a 3/4" shaft. The 1/16" does not sound like much until I tried to install a 3/4" coupler on a 13/16" shaft. Both boxs bolt up to the frame the same. My son installed the power steering, when he was using the truck. He went to a wrecking yard for the power steering gear box, it came with the coupler still bolted on the gear box. The coupler is interchangeable on the steering shaft but not on the box shaft. This is according to the NAPA dealer, I will go to exchange the gear box in the morning, and verify the sizes.
