Do you still have the old canopy? I've done a lot of work with Fibertech N More (used to be Stan's Fiber Tech) and they will do whatever they can to help their customers. Their website (
www.fibertechnmore.com) doesn't show the canopy you are looking for. But I know that Rick and Brenda will work with customers like you who need replacement parts for planes. If you still have the old canopy you can send it to them and they will reproduce it, even if the old canopy is in pieces they can reproduce it. Shoot them an email or give them a call and see if they can help you out.
I've received several canopies from them and they do a good job on them. I've got a canopy for the Top Flite P-51 and the Top Flite Bonanza and both are great quality.
Hope this helps
