Has anyone seen or added a backrest to a seat that doesn't have a backrest option? I have a Mustang seat w/o the backrest option and to add a Mustang backrest I must buy a new seat that allows one to connect.

Before having to buy an entirely new seat I wanted to inquire about what others may have done. Also, if I have to buy a new seat, any opinions of other brands than Mustang that have a backrest?

Thanks

I chopped up some old sissybar side plates to make brackets to use it as a rider backrest.

don't have any close-ups but here is a pic from the side.
