Pitman Arm Question?

Just checking, but is it lined up with the key spline on the steering box shaft?
Clean all if any paint off, small brass tooth brush and brake cleaner works.
Then lightly grease.

Yep. Checked that many times.

The output shaft is

Post a picture of the box and a part number.

Here is the Steering Box. Only Number I could find on it was stamped B0830H

Output shaft measures 1 1/8 Inch across the large Splines.
Both K7074 and K7075 Pittman Arm hole Measures 1 3/64 (Just under 1 1/16) across the large splines.

With the splines lined perfectly, It will not fit as the hole is smaller than the smallest part of the shaft. The hole is 1/16" smaller than the smallest part of the shaft.

I do hope I am missing something simple but I have bought 3 pitman arms (7074, 7075 and 7076) now all 3 will not fit.
