Where to Locate PS Gear Box for 64' K10

[aotte1]

Adding power steering to 1964 K10, using CaptainFab adapter plate. Using a Corp. 10 bolt out of a 1983 K10, along with steering linkage and gear box. Working on determining where to locate the gear box with Captainfabs adapter attached on the frame. Below are some photos where I have it located as a starting point. The gear box/pitman arm is located center ( wheels straight), the pitman arm is pretty much straight out from the frame. The drag link has a slight angle to it. The photo showing reference distance 12.75" could be shortened by about 3/4" by adjusting ( shorting) drag link.

If somebody has already done this to a 64 to 66 K10, would appreciate any photos, measurements on where you placed yours.

thanks,
