A few more photos, that show location, now that taking it apart to go have it all cleaned soon. The next set of photos shows measurements from center of bolt hole for attaching steering gear box.
Posting lots of photos hoping some will help show where it is located on frame. If you need more infor or photos let me know.
The adapter plate is only tach welded for now, will finish welding once frame is disassembled.

Note: In the first and second photo you will see on the bottom of the frame, front sway bar brackets from the 1983 K10, that are being added along with power steering. The sway bar brackets will be bolted to the frame as it is disassembled, to give access for drilling bolt holes.

Note: This steering gear box is 3 1/4 turns lock to lock, it should be the same from '83 to '78, maybe more years. Those are the only two year boxes I have tested.
