Rough cut the rear canopy to size and checked fit one last time before drilling holes. Pre-drilled #30 through the rear skin and the support strips for the Plexiglas. Re-installed the canopy and aligned to front roll bar. Began drilling the holes per plan (center front to back, side to side) until all was drilled and clecoed. Removed the canopy and did the final trim to the cut line on the roll bar. Deburred both sides of the Plexiglas holes. Did a test close of the front canopy and I will need to do some minor trimming between the front and rear half canopy where they slightly overlap
