Even if the frame was bent. I'd expect your settings to stay from before and after a test drive.
The pads on the alignment rack must be free. This was allow the suspension to settle after every adjustment.
I know a tech who spent almost an hour just to set the toe. Turned out to be the pads still had the pins to hold them still in them. Once they were free, it was a couple minutes.

my 1st thought was that the UCA cam/bolts werent being tightened enough but there was a(similar) thread way back & iirc something was loose in the LCA or was bending & he was pulling his hair out until he caught it.

I had a '70 Swinger do the same thing. The mount for the right side LCA was broken out of the K-frame. Pretty common on A bodies.

To re-iterate [in part] what others have already said:
1. If the problem were simply inexplicable height changes, I would recommend revisiting at what height the UCA and LCA bushings were tightened (they are supposed to be left a bit loose, then tightened at normal ride height). Also, to inspect closely the REAR anchor points of the t-bars, which need to be solid and immovable in their mounts.
2. Since the problem also involves a noticeable shift in camber (which is how I interpret your description of the tire "leaning"), you need to look for something in a suspension component or attachment point that is supposed to be solid and immovable, but isn't. Something simply bent, but not shifting isn't going to cause this. Inspect carefully the point where the LCA pivot meets the K member - are there any cracks, or is the welded tube in any way loose? What about the condition of the LCA bushing itself? Continue out the LCA to the lower ball joint, looking for anything cracked, or loose. Do the same inspections on the upper ball joint and in along the UCA. Look closely at the point where the UCA eccentric bolts are. Are the bolts tight, the bushings intact, and inner fender and related structure solid and uncracked?
A thorough and careful inspection is in order. That being said, my money is on the structure at or near where the LCA pivot shaft is anchored.
Down to just a blue car now.

Well i'll check that this weekend, the tube thats located in the k-frame that the lower control arm stud goes through. Does someone repop these tubes?
The tube doesn't crack. Its the weld that holds the tube to the K-member stamping
