We stopped at Colaw RV salvage in Carthage, Mo last weekend. You can buy almost any style and year of driver's and passenger seats you want there.
I saw everything from leather Flexsteel 6 way power seats to upholstered manual seats that looked like they came out of my old '89 Sportscoach.
The only thing they didn't have in the way of furniture was a double recliner couch that somewhat matched the current furniture in my coach. :-(
