A while back I bought a Saginaw power steering box that I thought was the right one for the kits that use a pickup steering box.

I got to looking at it today and discovered its a little different than I needed.

The casting number (7802644) appears to check out as the right box, but the output shaft is different and does not match the pitman arm for the correct application.

Instead of being splined all the way around the shaft with a threaded extension for the nut to hold the pitman in place, this one is splined only half way around the shaft and has a groove perpendicular to the splines for a lock bolt or something similiar.

The box has the correct mounts and the correct motion.

So here are my questions:

1) Any idea what this box is off of? Or could someone have modified it?

2) Any idea where I'd find a pitman that would work with this box?

3) I have another Saginaw box with the right motion and wrong mounts AND if the picture on RockAuto is correct, the right output shaft. ('76 Cadillac DeVille) Can I swap the output shafts?

It looks like the rebuild kit is much cheaper than buying another box and if its that simple I'll just go that way...

This is what the part I'm worried about looks like. Saginaw Output Shaft

It's true. I really don't do anything but browse the Internet looking for trouble...
