What kind of work are you looking to have done? Keep us updated with results. I might be looking at re-cushioning and recovering my bench seat in my 1951 F1 with something that isn't off the shelf.
With that said, I have recovered a few seats. I am about to reupholster my 69 Mustang with a pair of Mach 1 highback seats, TMI upholstery and foam.
