1968 A body 10" x 1-3/4" brake hardware?

Ok I've been looking for days for hardware for 1968 10" x 1-3/4" brake hardware for a 1968 Barracuda. I haven't been able to find it anywhere. I know you can get it for 70 and up Darts but haven't seen it for the older A bodies. I know the hardware is different. Anyone have any sources?
