The 11.75" rotor was used on 75-81 B and R bodies (St. Regis, Magnum, Charger, early Cordoba).
You need 73+ disc spindles to use these, or 70-72 B/E disc spindles with Dr. Diff's spacer kit.
NO FJMs came from the factory with these brakes.

I suggest you find the proper caliper brackets first. Everything else is available new. Without the brackets you're dead in the water. Canadian Tire can get you the rotors - ask for '76 Cordoba - p/n 013-4311-6 at $61.83 each (on sale). Name brand, made in USA. I don't think there's a better deal out there. Likewise with the bearings and seals. I need a set of brackets too so if you come across a couple sets, let me know. I'm leaning towards the "slider" style.

1979 Dodge st. Regis , or a Cordoba , any of the Dippy/Grand Fury cop cars ...
nope, ALL M bodies had the smaller 10.875" rotor....
'76 up B's, all R's used the bigger rotor.
I agree too, get the caliper adapters before ordering rotors. the rotors & caliper adapers are the only difference between an 11.75" setup and the easier to find (on all F/M/J's) 10.875" rotors.

Another question.. when I priced the caliphers for the St regis I was asked if the mount was front or rear{of spindle } ?? Two mounting locations.. therefore spindles are different ?? I have yet to find donor vechile.
no the spindles are not different , the calipers are different , you can swap the spindles to either side . you want calipers that are mouted with the bleed screws at the TOP of the caliper

Take a trip to the junk yard and look for Cordoba type cars or Diplomat type cars. Cordobas have the larger rotors, but either will work on your Challenger. What you are looking for is everything between the upper and lower ball joints. This will give you all the brackets,rotors,calipers,brake hoses etc. Then have the rotors turned and go to the parts house and get all of the new parts (calipers,hoses,pads) for the application that you have.
