I have my seats apart to replace the foam and reweld 3 nuts for seat back adjustment. The springs were sprung from either lots of use or a large rider, so I tightened them uo. While working on the springs, I noticed one side of the bottom channel seemed to be bent towards the center. Since I had the springs off, I squared up the channel. When I removed the other seat, it also had the bent channel. Is this a typical problem or was it supposed to be bent? Other than the slides the only thing under the seat is the seat belt retractor. Was it bent for clearance?
My 76 was the same way, like you I straightened the drivers side frame before realizing both frames were that way. I plan to put it back to the way it was, as I believe this is normal.
