Torsion Bar Problem!?

The pin looks to be in all the way. I believe you used a three piece bushing kit on pre 73 strut rod. This holds the control arm back and won't let it seat in the k-member. Check to see if the front threads on the strut rod are coarse or fine thread. If they are fine thread you will need to get the correct strut rod bushing set. They are thinner. Most are usually one piece but there are son slim two piece. The two piece with steel sleeve are for use with 73-76 and will cause your problem. I have had kits packaged wrong from just suspension. They sent me the correct bushings.

The first pic below shows the rod length difference. This looks to be the same distance you need to make up. I good be wrong without seeing more pics but This is worth a look. I have done the same thing in the past so I know first hand.
