Do the frame and forks have to match? I've got a postwar Montgomery Ward/Hawthorne frame, but I got it without forks. I have some forks that match in paint/patina fairly close, but I have no idea what bike they're off of. So, as long as I'm not modifying the frame and forks, is that allowed? This would be my first ever Build Off, but I just want to be sure I'm not breaking any rules or entering the wrong class.
