i love and live for project bikes and it looks like you got two very good ones. i myself have 15 bikes and four of them are "project bikes". the ducktails sound perfect and i concider 70's to be classic. heck, my black 89 huffy with chrome fenders, fatty white walls and longhorn cruiser bars turn alot of heads, but technically isn't classic. build it up like new or customize it with your own ideas, and don't be afraid to be original.
