With previously roughly trimmed ABS panels, sanded and trial fit starboard side main and center ABS side panels. Used 4" belt sander and 120 grit to remove flashing from back surfaces. Removed select section of edges in same fashion to open passage for rudder cable and top 'ledge' to fit longeron.
Found that thinning the ABS material on the corner with the sander, then waiting for the ABS to cool provides a clean edge for breaking off flashing material.
It appears likely that tabs with nutplates may need to be installled to secure panels.
Unable to determine where the "luggage closeout" panel fits.
