Austin, I know that this may be more work than you're wanting to go through but how about converting it to something more modern.
I would like to suggest that you put a seat and brackets in it from a TJ. Mine is a tumble up. It's easy to flip forward and snugs down securely so that I can feel confident that my passengers are safe.
It shouldn't be too hard to do the conversion, it's four floor brackets and a seat. Back seats aren't that hard to come by and if you get REALLY lucky, the upholstery material may switch from one seat to another.

It used to be a jeep thing... til that sh!t broke!
