There is a tech bulletin on the subject. In fact there are 2 on the shoulder belt restraint system. You can find the titles on http://www.alldata.com/TSB/19/91192054.html but you have to pay to get the full Tech service Bulletin.
Maybe you know someone at Autozone who can get it for you for free. Lowe's has a Teflon spray that leaves no residue. It's in a spray can.
Once it drays all that's left is teflon. You could try using this in the track to loosen up the belt. There is a switch inside the door next to the latch.
It is the switch that controls the shoulder belt. Mine tore up a while back. I wired in a manual switch.
If I remember correctly, it switches to ground when the door is ajar, and to 'open' when door is closed.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
