Fairing with West 407 filler to base of windscreen to upper skin and around side and upper rim of windscreen. Leveled out front of doors to cabin top. Trimmed fit of front of door to cabin. As others have done, I placed nutplates on the outboard surface of the seat locking mechanism. I can now use a socket wrench to remove the bolts from the inside of the seat rather than trying to place a socket wrench between the locking mechanism and the side panels of the cabin.
