4x4 Pitman Arm Information Request

[BigSix]

Evening Folks,

Just curious if there is any data on 4x4 power steering pitman arms? I tried searching and may have missed it - but I didn't find anything. I have a 1969 power steering box and need a pitman arm. What year 4x4 trucks can I pull the correct arm from?

I looked on Classic parts and came up with this steering box that is supposed to fit 68-76 trucks.

Then I look at this pitman arm and it says that it will fit 70-91.

I am a little confused as to why the steering box is listed to fit your truck but the pitman arm isn't..............

That's all I got !! I would buy the pitman arm above and see if it works,,,, if not ,,,,,,, return it.

Thanks for the info. I can't image 70 and 69 are different? Either way I am trying to find a list of years I can use to pull one from a yard because I need it Saturday and no time to order. Hoping someone can chime in that can confirm the exact years to start the hunt on.
