The Dispatch | Expert | Scudo Hub

Looking for a bit of guidance hopefully. We've picked up a '98 Expert with a Stimson Tirol conversion, but at some point the drivers side swivel has been removed (passenger one still there & working) and the single rear seat & base on the drivers side.
So we're looking for a swivel for the drivers seat and a rear passenger seat (and base it bolts to if possible) we know it's hard finding this stuff, so any help/advice appreciated.
If I could figure how to post a pic on here, I'd post a pic of the seats that are in it.
Thanks in advance
