Early CAV Mono Front brake disks.


I was at a car show last week and a fellow with a street rod had very nice 11-inch slotted and cross drilled rotors with PBR Cobra calipers. The setup appeared to be similar to my early CAV mono. He acquired his brakes as a kit from one of the catalog houses and he thought it was from a Mustang II. Does anyone know the original source for early MONO brake disks?
