Firefighter,
I've got a split bench (driver's seat moves, the rest of the bench is stationary) in my '66 C-10. I believe it's out of an '84 Chevy pickup. To the best of my knowledge the interior dimensions haven't changed much since they lost the Fat Fenders. The floor is flat, so just about anything should fit. If ya like the Dodge seat, I'd hit the salvage yards for one of them.
