I removed the back rack on my Polaris Sportsman per manufacturer’s instructions to find out I did not have more than two holes that I could put Lock and Ride fasteners to hold this “not a seat, but we know it is a seat / storage box” to the unit.
So I decided to use “J” hook bolts to hold it in place. It takes a little longer to install and remove but I have time.
The “J” hook bolts needed to be spread a little bit to fit over the one inch tubing.
