PS Pittman Arm ???

Hi needing some help locating the correct pittman arm please. I am doing a PS conversion and using PS box 27-7504 from Cardone. I was told there are only two options when I started this but clearly not. The splines measure Output Shaft Diameter (in) 0.864 35 spline

I ordered Proforge 103-10050 and its way to big. Please let me know if you have details on which one I need. Truck is 2wd drive 1967. column has been shortened. thanks

Pitman arm solved. Now fighting 1st gear with new column, will try lengthening the shift rod. Reverse works fine. So far PS works great. I did the Volvo pump deal and it was not terrible.
