Today I cut the curvature on the fuselage rear window and sanded all the plexiglass cut surfaces. Then I marked and drilled the F-631A aft canopy channels for the retaining screws. I also fitted the canopy inside the "ears' on the C-702 skin to fit check the canopy again. I had to make a relief notch in the skin for the plexiglass to fit better and found more trimming of the plexiglass will be needed.
