Spent some time riveting the canopy skirt to the frame and also sanding down the guide blocks to allow the aft nuts on the side windows to properly clear the blocks. After what seemed like a lot of sanding, I finally got the canopy to open more easlily but I am still not fully satisfied with the fit. Needed to slightly bend out the bottom edges of the canopy skits to fully clear the side skins below when closing the canopy.
