Ford passenger cars from 1963 to 1966 are basically the same. they were all based on the Ford Falcon unibody. Parts are every where. You can buy parts for a 64-66 Mustang, which are in abundance, and bolt them right up to your Falcon. They dont hold that great a value unless mint with low miles and all original. Its not necessarily a desirable car like a Mustang unless your talking to someone like me who loves oddball classics, like my Comet. The Falcon is light, oddball and fun to drive. Drop a V8, C4 and bigger rear end in it and have some fun. It will probably bring more value at resale like that any way.
