Manual steering gearbox

Reread post #2. Send him money. Get steering box.
We are talking on PM. I want to make sure I get the right one the first time I'm talking to another guy about a centerlink.
In another thread a member told me that he had first had experience with a small shaft manual gearbox and his 74 pitman arm wouldn't fit. So I am either gonna have to get the larger pitman arm or the centerlink either way I'm ok with that.
