pitman arm for 4x4 power steering

[synner88tc]

I have been searching everywhere and can't find a definitive answer on this.

I have a 71 4x4 jimmy with manual steering that I am trying to convert to power steering. Trying to source my parts before tearing it down.

I know that the pitman arm is different (larger shaft opening) for manual and power steering on 2WD gears but is the pitman arm different on the 4x4 gears?

The only place I have even been able to find a pitman arm listed for sale is LMC and they have one part number 34-2230 listed as W/power steering but they don't reference a manual steering arm.

Just trying to figure out if I need to order a new arm or if I can use the one already on my manual gear when I swap in the power steering gear
