Alignment Specs
#11
More caster = more return to center. I would be tempted to adjust the rear heim joint on your UCAs shorter.

Is it together enough to drive?

I am a few days away from driving it. Doing such an adjustment requires full removal of the UCA, a bit of a hassle. I may just shim the front UCA to tower mounting bolt.

2.5 should be fine for your caster. I would drive it before messing with shimming the UCA, which will affect the camber. If you don't like the way it handles then try it.

Dropped the car off the for alignment this morning. The owner had his old 51 Ford Shoebox 2 dr there and took me for a ride in it. Very cool car running a flathead V8. I was surprised at the power it puts out. Then we took mine out. He was impressed with the power of it. Said he could dial in the alignment so it will handle as close to a new car as it is able to. It also needed new front tires and he suggested a slightly different tire size on the front. I will post the results once I have it back and test it out. I wanted to stay and watch but I had some things come up at the office I had to get back for Sad Damn work getting in the way of fun.

Got the car back. Here is where it ended up and after some spirited driving on my way back to the office I am ecstatic to say the least!!!

Toe in .22
Neg Camber 1.1 on both sides
Caster of 2.5 on drivers and 2.85 on passenger (not quite as much as I wanted but couldn't get there without shims and he did not want to go that route as it would have caused interference with the stabilizer bar)

Like driving a giant go cart in the corners.

THANKS TO ALL FOR THE ADVICE!!

Just to add to this topic, I just got my alignment re-done. I had installed my rebuilt Saginaw 800 PS box back in February when it was actually warm enough to work in the garage. Problem was I really needed to replace the rag joint, but didn't buy one till a couple of weeks ago. Bought the Lares 201 from Rock Auto, which was just installed today. Fit on the input shaft was a bit too tight just to push on, but no problem with a gentle tap. Fit to the steering shaft was good, Job done.
When the car was last aligned, the tech followed the high-tech computer which is best on modern cars, but with a little persuasion did what I asked.
 Here are the numbers on my 71 Mach 1 with BFG tires @32psi, stock replacement front suspension.
 Caster: Left              2.2
             Right            2.7
 Camber:                  - 0.1
 Toe:                        1/32"
 Thrust angle;            -0.1
There was some secondary angles that mean little, just what the computer spits out. Problem with these High-Tech alignment benches is they can be too sensitive to vibrations, drafts and the like. Bottom line is the car handled much better and the steering returned to center way faster. I do need to get the car out and really drive it, but that's for another day now.

I can update my experience and it has been fantastic. On my 3rd day of hot rod Power Tour. Car handles great. Windy back roads are a blast and 80-90 on the interstate is like a dream.

Those look like marginal numbers given what I have been advised to work towards. Glad to read you are happy.
