Disc breaks from....what???

[42willys]

Hey guys, i'm looking for a disc break set up and loacl mopar guy has a set, but.......he cannot recall what they came off.(yes a mopar) It has the
knuckle, caliper and rotor only, no control arms.(well part of a lower)
there are no #'s on the knuckle what so ever for me to refrence.
the only thing I could see was on what was left of the lower control arm was a press in ball joint w/the # 9124 on it.
I did refrence this to a volare, 73+ charger, monaco, st regis and mangnum.
again the lower bal joint is a press in not the 1 piece old style.
oh and 11" rotors
any ideas how to figure out what it came off of:study:
and please no pound salt comments..ha!ha!

Fairly easy to ID if you know what to look for. If it is the 894 dust cap then it is a 1973 or later. Or you can measure the inner wheel bearing. If the rotor is a uni-cast setup then that tells you it is a later model. The screw in lower ball joint tells you that it is a late B or maybe a C body car.
