57 Vroom vroom,
I'm not sure what rotors are used, they are 11" and appear to use the same bearings, calipers, pads, & brackets as the 5 lug conversion on my 56 which uses components from mid 70 Malibu/Camaro/Cutlass cars. As far as I can tell the only difference is they are 6 lug. ABS has a shop where they install brake & steering conversions and they have come up with a number of inovations. Some of the early foreign trucks had a 6 lug configuration but I don't know if they are used in this instance.
