Like you I don't know all the names of the front end parts, but where the sway bar connects to the lower A arm (I will call it) it has the same type of rubber bushing and clamp as where the sway bar connects to the frame rails. It sits lower than your connection.
As far as how far the pitman arm goes on the steering box shaft I have approx. 5/8" space. The nut that I used was the same nut as the manual box and it was quite a bit thinner than yours.
I am not sure if sway bars are different for 1/2 ton and 3/4 ton or not.
What pitman arm do you have?

You were correct when you noticed pitman arm did not go on far enough. Corrected, it will raise driver's end of center link--and tie rod ends--and should then clear both sway bar(if the bar is correct) and the frame when turning the other way.
Enjoy your project.

Thank you everyone.

The sway bar is from CPP (ADDCO unit) ordered specifically for my 66. No clearance issue on the passenger side, which is why I am suspecting that I have the wrong pitman arm. This pitman will not go any further onto the spline shaft.

Any chance someone could send me some rough dimensions on the K6131 pitman arm? I have not been able to find any dimensions on line yet. I may have the K6130 (manual steering unit), and I don't have the old pitman arm either. The nut pictured is a nylock nut from the fastener store... in my infinite wisdom I tossed the original pitman arm as well.
