Different arctic cat model chaincase swap?

[Polaris boy]

Hey guys I got a 97 arctic cat panther 440 touring chaincase piled up. I was wondering if the chaincase from a 1997 arctic cat ZR 580 efi would work?

I would be very surprised if it didn't fit. They will likely be geared different but otherwise should be the same case and cover.
