Power to Manual Steering Clarifications Needed

Hi,
So I'm considering a Gen 3 hemi swap, which requires a manual steering box, I have the power one. Not a big deal for me. I know there are 2 sizes of output shafts on the steering gear, switching in 73.
I have a 71 scamp with power steering.
My pitman arm, according to Moog (MOOG Suspension part numbers for Mopars) is the same for power steering and manual steering.
My questions are:
1) is my pitman arm the small style on my power steering? I thought power steering had a larger output shaft?
2) if it is larger style, can it be used on a 73+ manual steering gear?
3)what is the difference between the center links of a 73+ car that makes it a requirement to swap it if I use a 73+ manual steering box?I know pitman arms flip flop which side the nut is on.

I have the opportunity to get a manual steering gear for super cheap, but don't want to go with it if I'm spending money on a bunch of other steering components.

Thanks :)
