Installed the adjustable seat slides on the passenger side. Again, the rear nuts are hard to tighten but I have done 3 out of four. The fourth rear nut is posing a problem as the hole is very near the seat base support flange and hard to rotate. Will have to ponder this problem. Dean and moved the pilot avionics shelf L angle supports from above the instrument panel bar to below it. We had a couple of conflicts with switches so we drilled new holes on the bottom of the bar, tapped them, then used #8 screws. Next we cutoff a few inches from both ends of the instrument panel. This will allow the panel to drop down when we need to get behind the instrument panel. Dean had a couple of end pieces 3D printed that we will use to finish the panel.
