Jamooche,
Not that I am aware of, but Mastercraft makes a two-seater, bucket-style bench seat. It is a fixed mount and high-back, and probably the safest option. However, you would lose the flexibility to quickly fold/remove the seat. Also, the Mastercraft bolts to the floor only, with no connection to the side wheel boxes. I like the mechanical connection to the wheel box sides!
I'm thinking of sourcing some headrests from the junk yard, taking the seat cover/padding off, and weld the headrest mounts to the seat frame.
Regards,
