The biggest things will be:
- Any windshield height mods.
- Snaps used. There are circular, lift the dot and at least one other type.
- Position of snaps. Some slide in the windshield frame, others are hard mounted. They are not copy exact, so many won't line up. You'll likely need to add additional.
Give A&J Canvas a call and see what a new one would cost as a compare. Likely in the $2600 range. If you can get it cheap enough, go for it. Just make the mods on the enclosure not the boat (i.e - make the canvas fit the boat, not the other way around).
