Installed an L angle between the seat base and arm rest tunnel. It proved impossible to rivet the seat base to the arm rest tunnel with the provided holes. I would have had to pull the torque tube but that was not going to happen. I was able to pull a couple of rivets next to the stick only. So I cut a piece of L angle, drilled holes, and riveted it in place. Next, I installed the adjustable seat mechanism which I sized and drilled the holes a year and a half ago. The two rear nuts are very hard to tighted because of clearance. I will work on them tomorrow.
