Pitman arm help please

[Craftsmen]

Okay, I have a 1970 c10 short box with manual steering, time to go power. I went to advanced auto and purchased the power steering pump and gearbox for the 1970 c10. I read in the forum that I also needed the new rag joint which they had. I also read I need the pitman arm. They had to order the moog pitman arm because they didn't have one on the self. I got home held the new gear box in place and noticed I had to notch the front bumper bracket to clear, done. I bolted the new power box in place, noticed it takes four bolts not three. Done. The new power steering box spline shaft sets way closer to where the pitman hooks up. My question:
Can someone tell me the difference between the manual pitman arm and the power steering unit arm? Is it a short little thing or am I missing something?
For the pump mounting I'm installing a v8 instead of the six and plan on purchasing a serpentine kit. Probably buy the hoses from Paul's, etc.
Thanks for any help, always very much appreciated.

Oh and forgot to mention my truck has all for wheels off the ground supported on the frame with jack stands. My truck have the ECE 4/6 lowering kit.

Rock Auto shows different pitman arms.

I just measured, the spline coming out of the power box is like 1-1/4" and the manual box is like an inch.

Moog K6130 Manual Steering
Moog K6131 Power Steering
Unfortunately, in this day of online cataloging. the Moog website does not show/tell me specifics in order to tell you the differences.

Here is where I bought my last one from.

Yep, ordered the k6131 moog. Someone said I may need the idler arm also? By the way those measurements in my prevoious post were diameter.

Yup, just did this, you will need to borrow the puller and a torgue wrench when re-installing.

I could not see a difference between them. I ordered and used a new Moog Pittman arm-recommended for a PS gear box, but could not see any difference between the new one and the old one--unless the spline count is different. That I did not check that. Both used a 1 5/16" nut.

Thanks a lot guys, you were a big help as always��

For some reason I thought some told me the spline count was different for power and manual.

Power has a larger diameter spline
