these mirors. its a handle end mirror for 7/8". says it fits polaris. hope so since i cant even get to my bike for another 2 months.

 

Looks like they would work, the expansion end looks beefier than the polaris mirror. I have the Cabela mirror ( same as Polaris) I've had them on over 250 miles now without coming loose. I cranked them down pretty hard and check them after each ride.
