WTT Mustang Seat for Mustang w/backrest

I have a Mustang seat without studs and without a drivers backrest. I am wanting to trade mine + cash for a Mustang seat with a drivers backrest. If for some reason you have the seat that uses a backrest, but no longer have the backrest, that is fine too. I bought a drivers backrest on ebay a few months ago in hopes of ending up with a seat at one point.
