Pitman Arm Question

[Berndtc426]

So I searched the sight and found a few threads about what pitman arm to use for crossover steering. But what I didn't find were 2 answers that were alike. So here's my question...On my 72 GMC with a dana 44 front axle I want to install crossover steering. I've pieced a kit together but can't seem to figure out what pitman arm to use with the 2wd drive box I have. I have approx 7 inches of lift. I've heard that I can use a ford bronco arm, but no one was specific on what years would work. If anyone can tell me which pitman arm will work for me, or point me in the direction I should be looking I would appreciate it.

Thanks
