Cushman Scooter engine shroud?

What's the difference on the Cushman Scooter engine shroud (cover) husky motor? It looks like they will all work.

I have 7 old Cushman Stepthrough Scooters, all rebuilt except one, and they all look the same.

Your best bet for answering this question would be to join a cushman scooter forum. Go to the yahoo main page find Groups and search for cushman scooter. there are probably several. You may have to join, but, its free and will probably be a wealth of information
