I found the sidewall trim panels interfered with the seat slides preventing easy adjustment of the seat position so I unglued the carpet in the appropriate areas, trimmed the fibreglass & re-glued the carpet on both left & right panels. The front bottom corners needed trimming to clear the rudder pedal mounting channel too. I also installed an additional mounting rivnut/screw low down & behind the large map pocket as the panels were not sitting nicely against the inner skins in that area. There are two access covers for the main gear mounting bolts, they each needed a couple of screw holes opened up slightly to allow proper fitment, did that too. All the trimming has made the panels fit much better. Lots of work hours for not much to show but worth doing none the less.
