I drilled the hole for the clevis pin in the C-661 slide block and installed it on the canopy frame. I taped three 6 inch long 0.40 aluminum strips to the canopy frame and made several minor bend adjustments to get it to fit flush to the fuselage sides. I positioned the side rails ensuring they were both centered on the fuselage and parallel to each other. I taped the rails in place and will drill the attachment holes tomorrow.
