Question about torsion bar adjustment

When I installed my new pin and bushing into my LCA, I was able to pivot them independently of the LCA. It would pivot until it hit the adjustment bolt. The torsion bar mounting point and bushing/pin are one, and the LCA is actually separate (in a manner of speaking) right?

If You take the load off the torsion bar, and then proceed to remove the shock bolt and lower ball joint, does the LCA not have the ability to drop straight down? The torsion bar does not move with it. Or am I forgetting something.

Not trying to cause an argument or anything, just trying to cement my understanding of the operation. I really appreciate the responses.

Also, I just looked at the 66 service manual (don't have my 63 manual here) and it makes no mention at all of loosening the pivot nut. Just to make sure you jounce the car up and down numerous times after each adjustment to determine height.
