Drill holes in canopy with plexiglass drill lining them up with holes already in the frame. Final drill all holes larger with a #27 plexiglass drill.. Mask the canopy with a border and paint black for looks. Tap and attach guide blocks C-1207 into F-1254Lb & R. This will help guide the bottom of the canopy so it lines up with the fuselage frame when you close it and keep it in place.
