    Appreciate it. Yeah it was a pain in the ass...most of the time but yesterday I was out and someone on thier cell phone cut right out in front of me...dialing (yeh) . I had to step on the brakes right quick and the nose went down and we promptly stopped and catastrophe averted. The drums wouldve prob stopped us too, but wouldve taken longer...and then theres the fade issue. Yeh worth it.

    Oh...and she gave ME the finger. Really?

    Without reading more than the first page I'll put my 2 cents worth in
    I did our 58 Polara with 73 New Yorker donor
    I have a power unit but have never had to use it
    MANUAL WORKS FINE
    that's the easy part
    what your really have to do is to change the rear wheel cylinders to smaller to prevent rear wheel sliding (or if you have front wheel lock up first go bigger)
    or an adjustable proportioning valve
    I'm using 15 x 7 cop car wheels (and V rated tires)
    Would recommend these as a minimum width
    Today go 16 or 17 to get the wheel away from the end of the A-Arm = and wider but with reasonable back spacing.
    I'll post on a D Body conversion later

    Thanks

    If I may, gentlemen - I went through this whole thread and didn't see mention of my favorite C-body trick, which is "re-rotor"ing '69-'72 disc brake hubs with an inexpensive rotor you can buy right now at any parts store. You don't have to look for '73 donor cars to do a swap, or you can reduce the cost / labor on your '69-'72 car if it already has discs.

    It does require a bit of extra work the first time you do it (breaking out the studs and checking the hub face for runout), but those are one-time efforts.

    Autozone part number: 5312
    NAPA part number: NB 4885743
    Interchanges if neither of those stores are near you:
    Dodge Truck -> Ramcharger-AW100 1/2 Ton 4WD (1974-1981)
    Dodge Truck -> W100 1/2 Ton 4WD - Pickup (1974-1977)
    Dodge Truck -> W150 1/2 Ton 4WD - Pickup (1977-1981)
    Plymouth Truck -> Trail Duster (1974 - 1981)

    Write-up I did with more info: Only slow cars need excuses.

    Sorry, that was over ten years ago; I have no part number for you. My parts man (now dead), using an older catalog, found the part number and did a search for original '71 C Body rotors. He found two; one in Kansas and the other Illinois. Price for both was over $400, but for me was well worth it.

    The difference between the '73 and newer rotors and the older ones is one-piece verses two-piece. The latter are very expensive if you find them.

    AFAIK they are now doing 1 peice unicast rotors that are machined for the smaller 69-72 wheel bearings. They are a little more money than the 73 style but nothing like an OEM style 2 peice will set you back.

    I really like AF's solution above using Ramcharger/W150 4x4 rotors retrofitted to the original hubs.

    What does that mean?
    Which original hubs (spindles)? The drum or Budd disks?

    Neither. 69-72 disc spindles used a 2 peice rotor.

    AF's post is 4 above yours. There is a link at the bottom to his post detailing the procedure.

    I can't believe someone hasn't figured this out before, especially when the only option was NOS $150+ rotors.

    I've not actually checked the new unicast rotor that is supposed to fit the 69-72 application to verify that it isn't just a 73 rotor in a different box but assuming it's correct for the application, chances are your local Autozone is more apt to have the 4x4 rotor in stock.

    It opens up a much larger supply of spindles now. I got the last set of 73 spindles out of my local vintage boneyard for my 66 but there are still several of the 69-72 variety in stock for when I convert the wagon.

    Guys, I think I'm going to take on another project...drum to disc conversion with OE parts. On my '69 300 'vert.

    I fell asleep last night reading through this thread and some other articles I found on line. I just want to get the correct parts the first time round lol

    Based on these two threads here, would either one of these spindle sets work? RA shows calipers, rotors still available for '72 and '73s, so that's not an issue.

    These are my two choices so far....

    For Sale - 1973 Spindles

    and

    For Sale - 1972 disc brakes

    Would a '73 Coronet spindle work?

    Thanks for all your help!!

    Coronet is a B body, I believe only the C body will swap

    Thanks! I just bought the setup from Barnfind. Thanks to all the other guys that had offered up parts!

    Barnfind's stuff came from a 72 c-body. I believe 69-72 c-bodies used the same parts. I hope, as I just got it. lol

    Off to do some more research on the smaller parts over at RA and ebay.

    Thanks again!
