Fabricated guide blocks. Located and drilled holes in roll bar, then tapped. Secured guide blocks to roll bar with screws. Had plenty of interference between aft nut and lower outer edge of both guide blocks. Aggressively trimmed lower outer edges of guide blocks until canopy rotated open and closed without interference. Denise helped by holding canopy open while trimming guide blocks. (page 34-12, steps 1 through 6). Page 34-12 is complete.
