I have bult a mold for Temptation canopies, HOWEVER, this isn't a Temptation I don't think. The canopy would be fiberglass, not clear plastic, but it wouldn't fit what you have

Anyway, building your own from scratch is simple.....First carve a foam piece to fit the space. Sand it to a nice contour and make it ready to sheet with balsa. For a canopy, use 1/32" or 1/16" soft sheet, well wetted to allow easy bending, and then wrap it over the canopy. Take an ACE bandage and wrap it around the work firmly and let it dry for a couple days. After it dries, trim the balsa and glue it in place with some polyurethane glue. Don't go crazy on the glue.....just a dozen dots to hold it securely. You can glass and finish in paint, or monokote it.

I have done many canopies this way. Also cowls....it really is that simple

Good Luck
