Installed the side skirts and checked for fit. It is very tight fit on both side. I see some rubbing along the middle or a bit forward of the middle on both skits. I spent a lot of time trying to adjust for this and had some improvement. The rubbing occurs at the last 1/2 inch of the canopy travel before it is fully closed. Drilled the screw holes at the lower edge of the C-601-1 canopy using a #30 drill bit, countersunk the plexiglass and enlarged the holes for #6 screws. Deburred the following: C-759 inside canopy skirt, C-660 canopy skirt, C-601-1 canopy (screw holes).
