    Have mine on. Should have cut more than .270 out of the inner bearing race. Had to take some material off the caliper to clear the rotor. All on now though with the new wheel.

    How the heck would someone go about getting brake parts for an aussie mopar? Rock auto sure doesn't carry them!

    Seems like the most Difficult part of the swap is finding a machinist. Ordered the rotors from Amazon. Raybestos 6004R. $83.56 and free shipping.

    Any one else have recent updates?

    Yeah I got mine done to the normal specs the same as what i posted on the previous page and got the suggested dust covers. They fit and work perfectly, no vibrations, no slop, mounted right up just has to grind away about 3mm from the caliper but that is easy peasy.

    While visiting my family in Oklahoma for a funeral, my dad and I met with his machinist friend. The guy is amazing. Can custom make ring gears, pinions, planetaries you name it. He’s done this type of rotor work in the past. Pallet loads of rotors that he machined down for some company back east. He’s semi retired now but got the good ol boy shop rate.

    Machining to be done

    1. 11.00-11.09” rotor diameter
    2. Inner Race seat machined down .271-.275”?
    3. Hub height to match Mopar original. Does anyone have the mic’d measurement for the original inner rotor hub height? Need to know how much needs to be cut down to match the Mopar originals. Thanks in advance.

    If all goes well I might get a few sets done and offer them here on FABO. It’s a niche market but seems like a great way to get BBP with minimal alterations.

    Wonder what people would be willing to pay for already machined rotors? $300 for a pair?

    What is the mic’d measurement?

    Just looking for the height of the original Mopar rotor hub or the finished product like in the picture you posted. I’m having the work done remotely through my dad and the measurements are all the machinist really needs. Micrometer measurement of what’s pictured.

    Oh right, Im not sure what that measurement is. I gave my machinist the new rotors and the original ones to match them to. I could measure mine but I dont want to give you an inaccurate figure. It might say farther back in the thread.

      Has anyone tried The Ram Man for his conversation rotors?

        I can't remember his price but to a capable machinist it would be a walk in the park hence me thinking he was milking a niche market. Fair enough i guess
        There's great buying for the combined hub,disc from Rockauto and others to get you started.
        Most people thinking about this mod are likely to have a Kelsey Hayes for the machinist to reference anyway which is always easier

        Ram Man was somewhere around $400-$600 a pair. They looked like they were based on the Mustang rotors, having had the windows in them.

        I just remember seeing them on his website, and then they were gone. I was a little fuzzy on the price, but remembered feeling it felt high.
