what pitman arm will work?

I am doing a p/s swap in my 71 and am using a yj box. Question is will a cj pitman arm work on this box so it doesnt have so much drop. say one from a cj7?

 

I have a tj box and I used an arm off of a fullsize jeep pick-up. IIRC, the sector shafts on all saginaw boxes are the same it is just how the splines and key ways are cut into the pitman arm. I tried using an arm off of a mid nineties ford box and the keyways were 90 deg from what I needed. There was a thread quite recently that talked about this. Do a search and I bet you will find a wealth of info on this.
