After ignoring abuses of its copy and trademark rights for decades, Ford now has an activity whose sole responsibility is to enforce those rights. Like Jerry says, the risk is negligible for one or two for your own use. Moving beyond that exposes you to the wrath of Ford, who has federal law on its side. They do, however, have a licensing process in place to grant you the right to use their trademarks on parts and many reproduction parts producers (Drake, Carpenter, Vintique, and Nacewicz to name a few) operate under this process. It involves the payment of a royalty, which is normal in such a licensing arrangement, but also the parts covered under the arrangement have to meet Ford's standards.
