Replacement seat belts for RTV900?

Any ideas for buying replacement seat belts for a RTV900. It looks like the belt ends bolt to the fram with 3/8" bolts.

So I would need a retractable end and then the belt receptacle at the other end.

I would think that this could just be a generic seat belt, not Kubota-specific (with Kubota-type prices).

Suggestions?

Thanks,
