In regards to the "A" vs. "B" and manual vs. power steering, I very well could have been mistaken. I did admittedly assume that the part in the previous picture, which has the "B" rev, was a power steering version. There were two reasons for that: (1) I pulled the complete setup from the power steering optioned vehicle, and (2) the vertical arm does not have the center third hole, and all the posts (that I remember) and cars that I've seen have me thinking that the two hole variety was power and three hole variety was manual. I suppose someone could have mated a power vertical arm to a manual horizontal arm.
The primary purpose of my previous post was to show that the Ford part number was part of the casting on the horizontal arm.
I like the idea of putting some dimensions in place, especially since I looked at the Moog replacement from 1980 that I have. There are some distinct differences. I'll put a CAD drawing together and post it.
As far as being too stupid to post pictures, how about a tutorial to post pictures? Naturally, the tutorial is in the pictures below.
One final note about attachments - I've noticed recently that if I create a brand new topic with pictures, it does not get created. I've been posting without the pictures, and then modifying and adding pictures as a second step.
