Joe,
Take a drive down to Tripp City, OH and talk to Jeff Rogers (owner of Airplane Plastics). He’s a very nice and helpful guy and can probably help you to save your canopy. If not they have “blems” if you only need the aft part, or front part. If so, you will need to deal with Vans on the purchase, but I’ve done that over the phone - twice. You’ll pay 2/3 of the canopy full price, but if Jeff isn’t busy, maybe he can trim it for you. I don’t want to speak for him, but he helped me out that way. Call first and bring your canopy and frame and they can put it in the mold to see how it lines up. They use the same mold for the RV6, 7, & 9 whether it’s a tipper or slider. You might be able to make what you have fit.
