front bucket seats on '68 Barracuda

If its square when folded and not square fully opened, the stops are the fault, one side travelling father than the other. Not many would go to so much study to find the problem.

Forgot to mention 3 of the 4 hinge nuts were loose from my seat frames. Just some small welds on the hex tips was all they had. I'm sure that could make some difference as well.
They won't come loose again.............
