Replacing the Canopy
Been there, and done that. If you used a Todd's canopy for the cracked one, then use a Todd's canopy again. If your first canopy was a Van's kit canopy, then I believe that you must use a Van's canopy for the replacement.
I carefully drilled the old canopy off the Doll without damaging the skirt. I laid the cracked canopy inside the replacement canopy and moved it around until it was a perfect fit. I traced it on the new canopy and cut it out. It aligned with the original windshield perfectly. I used a debur tool to cut the sharp edge off every drilled hole in the glass. I sanded the area on the canopy and the canopy frame where the glass would touch the frame. After the canopy was riveted on, I taped off the glass and frame, and I filled the gap between the frame's tube and glass with Sikaflex.
I'm just finishing the initialization of a Todd's canopy on a friends RV-8, and the Todd's canopy is NOT the same shape. It is a beautiful canopy, but I would not try to replace the original canopy with a Todd's canopy as the overall shape is different enough as to make the fit of the skirt, and alignment with the windshield, very difficult if not impossible.
