Seriously, you might talk to some folks that do vintage restoration. Patti
I agree with Patti. But I do wonder if you could expand your search for services. Call local companies who replace headliners, convertible tops, and limousine interiors. You might even try companies who offer leather upgrade services for local auto dealerships. I don't know how popular the practice is today, but years ago, many leather interiors were done locally after the car was delivered to the dealer. One more service comes to mind are conversion van companies.
Such places will likely offer different colors, vinyls, fabrics, and leathers. Stay away from bonded leather for that material loves to flake like you have happening today. Top grain leather is decent and affordable. Full grain leather is real quality but very expensive.
