Convertible body parts are different from the closed cars because the bodies were not Ford-built. Latches and window regulators don't interchange, either. When I restored my '47 convertible, the "treasure hunt" for necessary parts took more than a year. Ragtops were low production models, and very many lost out to weather, reducing the junkyard resources. If you do locate such parts, prepare to pay a premium.
