disc brake question

Small bolt pattern rotors are kinda hard to find but not impossible, check here for clues: http://www.earlyabodyforum.com/board/messages/394/1079.html

The calipers are available from www.calipersonline.com or you can rebuild them yourself, just order up pistons, piston seals and pads for a '67 Mustang...same stuff.

You might want to try Mustang rotors, there's a whole thread about that option, which requires some customization--> http://www.forabodiesonly.com/mopar/showthread.php?t=20544
