A good source for interchangeable parts are the Falcon, Comet, Maverick, Fairlane, Torino, Ranchero, Granada, Monarch and Versailles. There is a book that is quite expensive new, but is the industry standard for interchange parts, it's called the Hollander Interchange Manual. It's has it all. You may be able to find a copy at a reasonable price from a used book store. I believe that they are published yearly.
