It appears that the back to drivers seat leans to one side. As if a part is either broke or bent. I tried to find something already posted but did not really find what I needed. The seat itself is in fairly good shape except some wear from 25 plus yrsa of getting in and out of car. Is that part that is bad be easily removed and fixed or replaced. What would I need to replace it, part wise so I know what to look for.

 

The back rest portion of these seats are contructed with a solid bar
on the console side, and the latch-hinge that mounts on the door
side of the seat. With out some pics, its hard to say where the
failure is. The seat frame attaches to the floor with 4 nuts, on
studs welded into the floor panel. Take the seat out, & the problem
should be easy to find.

Good luck.
