Is there anyone making stock interiors for prewar Fords now? I know unused Lebarron Bonney kits are going for $$$$ when you find one.
Get a hold of Cl***tique (Model T Upholstery from Cl***tique Upholstery - Ford Model A & T Upholstery, Tops, Benches and Kits). They do Model A and the B is not that far removed. They bought out LeBaron Bonny when they closed up. Mike
