looking for a beter way to attatch my boss seat to the chassis

[ac m5]

Hi
I;m looking for a better or more secure way to attatch my new boss seat to the chassis because i have no garage and my sled spends a lot of time outside and i don't want my seat to get stolen. Anybody have any suggestions?
Thanks

take the seat off when your not ridding.
