The saga continues.

Absolutely nothing was going tomallow movement to that driver seat. With
help we pulled, tugged, pushed, all to no avail. Finally removed the seat
cushion, which had to be seriously repaired anyway, looking at the seat pan
sans cushion, it appeared the release rod was bent, though I really didn't
see how. That rod is some seriously hard steel. The crux of it came down to
cutting that rod to get it released. Removed the cut rod and guess what -
that bloody seat would not move an inch. Finally had someone lay on their
back and kick the daylights out of the back of the seat on both sides,
while it was pulled from the front. It moved a 1/2 inch. But it did move.
From then on it was kick relax, kick relax, kick relax. After about 40 -45
minutes of this the seat came off the tracks/ rails from the front like it
was supposed to. Inspection of the pan on the  underside revealed no loose
screws. How ever, that track was really chewed up. As were the seat guides.
Spent some time dressing up the rails and getting them smooth again, and
putting some grease on them. I was fortunate enough to have another front
seat handy with the same color and pattern as the original. It works like
its supposed to. Now  I am good to go. !
