I'm in the process of modeling my own.... If you can wait, when I get done with them I'll drop you a line or so.  I have no plans for the C64, and it depends on the type of joystick, but the floppy drive and 5.25" floppy disk, 8" floppy, and mouse, are some things I'm working on. Actually I might have a 3.5" floppy and drive laying around...
