Power Steering Conversion - Old Pump/New Box?
 

I have a '69 GMC with an L6. I'd like to add power steering. I salvaged the front clip from an '84 GMC that had power steering. Will the '84 power steering box work with an original power steering pump? I want to keep the original look under the hood.

The pressure will work. 84 used O-ring style metric fittings on the gearbox 68 used SAE double flare. find a 80 & up power steering line that is the length & bent the way you need & cut the pump end off use a 68 nut and double flare the end. down side is you have to do this every time you need a new line.

I put a serp setup off of a 94 Chevrolet pickup on mine. I am using the stock pressure hose off of a 72 with no problems

All you have to do is take a 1 inch wrench and unscrew the fitting out of the back of the pump and replace it with a later one that matches the box and hoses. They interchange.
