    I want to sell these but not sure what their off of. I was told looked like B/E, then told they look too big to be B/E and are C body, rotors are 11" and heavy. I've put in the numbers I can find and coming up with nothing. Calipers are pin style. One picture shows spindle in question along side of SBP spindle from 70 Duster. Another picture shows upper control arm next to dirty control arm from 70 Duster. Any ideas ? IMG_20190702_162547763.jpg IMG_20190719_183646505.jpg IMG_20190719_184049416.jpg

    Yup, look like Cbody to me, and most probably 69 to 72, maybe 73. B-body units are only slightly larger than A body. If you can measure center to center, the holes for where the lower ball joint bolts into and let me know I can get back to you after checking mine then.

    11" rotors are C-Body Rotors. '69-'72 used a two piece construction with a pressed on non-removable center hub from the factory. The '73 spindle is the same design as the '69-'72 except that the diameter of the spindle shaft was increased to accommodate heavier bearings. The spindle shaft for '73 was milled to about 1.45" for the bearing closest to the backing plate. If the spindle shows that diameter it is a '73 if, smaller it is a '69-'72, which is about 1.25"

    Rotor should be 11.75 x 1.25 thick if it's a Cbody. If it's just shy of 11"x 1" thick, it's either E or B and I'm not sure maybe Abody.

    Cordobas had 11.75 rotors but only 1" thick because they are basically a Bbody too.

    That is correct. Mopar referred to these as 11" rotors even though they were about 11.75". The B-Body units were called 10" rotors at about 10.75".

    Story behind confusion. I bought a 70 Duster from a Chevy guy who didn't know anything about Mopars. He started collecting parts for the big bolt pattern upgrade and I think someone sold him a bill of goods. This explains a lot. I have found several things that make me go Hmmm. I knew they were too big for my application. I've never delt with Cbody stuff. So what do you think for years and make. I can mic the spindles if necessary . Thanks for your help.

    Please measure and post the bolt pattern of the brake rotors.

    5x4.5`` = any from Plymouth Fury I to Chrysler New Yorker Brougham.
    5x5`` = Imperial, either a 69-70 Crown or a LeBaron of the range posted above.

    Their 5x4.5 I put my spare tire from my Dart which is 5x4.5 and matched up.
    Can you give me a guess on the Fury/Chrysler years.

    Do both of the rotors have right-hand threaded studs?
    If they do: 71-72 or 73, depending on the spindle.
    If they don't: 69-70.
