Disc to Disc conversion - will this work.

[69datona]

i see you guys are talking about something that i have been working on and i would like some input from you all. i have a 69 charger with 73/74 e body spindles on it i have been running 10.7/8 inch rotors for 20 years but now i wanted to change over to the 11 7/8 rotors off of a cordoba what will i have to do to get my caliper to work. i have been using to 70 charger set up with the two slider bolts all these years and would like to retain them but if i can't that's ok, i need help.  thanks 69 datona

Do I need later style ball joints? (it sounds like hemiRR didn't change them)

Do I need the distibution block? (remember I have early model power disks)
If so, where is it?

No, you current year ball joints are fine for this.

If you have disc currently, your oem dist block is fine. It is located under the master cylinder typicvally, where the lines from the master cylinder are split to the four corners.

You just need to find the larger caliper brackets. These came as both pin type or slider type so search around until you find the right match. Your looking for hte bigger cars, Corboda, Fury, Diplomat. Also, you'll need rotors, obviously. I think the 73-74 E body spindles already use the bigger bearing, so your spindles are fine.

what about power drums to power to disc would a person need a distribution block from a Disc car?

[b5blue]

All you need is a restricted flow to the drums in the rear.

Okay got my $50 77 Volare spindles at pull-a-part.  BTW - A guy showed up after the same part while I was under the car - 10 am on a weekday - what's up with that?

Anyway, two questions:

1.  Do I the use the part circled in yellow (what is it called? "steering arm") from the Volare or the Charger?
     (maybe a stupid question  -but..........) 1st picture.

2.  Can powder coat or paint be applied to all but the shaft or do I need to mask off the machined face?     
     2nd pic  - circled in Orange   (forum search inconclusive)

Thanks in advance.

1) the Charger arm is what you will need to use. You'll also notice that the Charger version also has the lower ball joint attached, unlike the F body version.

2) you can paint that face so long as you leave the shaft portion clear.

Yeah, I've noticed an increase in F bodies missing spindles in the last few years. It used to be no one wanted them, but since the tall spindle myth has been debunked, they tend to disappear pretty quickly.

I've got a quick question, I've got set of '73 Duster spindles and caliper brackets, but I'm missing half of the original mounting bolts. What grade are the factory bolts, grade 5? It looks like they have 3 marks and a logo in the center similar to the ones in stripedelte's pictures. I've already got grade 5 hardware, but I'll upgrade to grade 8 if needed.

Thanks

this is the kit i used on my 69 charger . everything is in one kit . great price . plus drilled rotors . all chrysler parts .

i kept  them manual brakes and they stop on a dime , great pedal too . . i painted the calipers black  . they look great .

OK, so I've been reading this all with interest too as I want to install disc brakes on my 68. I haven't seen anyone talking about using parts off of C bodies. I have a 70 New Yorker with disc brakes and was hoping to at least use some of the parts on my Charger. Just haven't determined yet what parts will and will not work. Also bought some 70 something A body spindles several years ago.

If  your buying all new stuff, it only costs a few pennies mrroe to get grade 8, so I'd go with that.

C body parts don't work on B bodies. Bigger ball joints, bigger pieces which results in different geometry, bigger bearings, and I think a bigger bolt pattern.

[Iceyone]

Is was speaking more of the actual  C body brake parts such as rotors, calipers or anything else.

[HPP]

C body rotors have big bearings that are incompatible with B body spindles. They also are 1.25 thick compared to 1" on a B body, so the caliper is a mismatch too, unless you use spacers to move the pads out. I also think the mounting pattern for the calier adapter is different.

  Will the parts from a diplomat work on a 72 charger? I have the factory disc brakes and they're e x p e n s i v e!  Wanted to upgrade using cordoba parts but I haven't seen one at the pull yards.

As stated, you can either use the spindles from a 73-76 A body which are exactly the same height as your originals or the later ones which are 3/8 inch taller.  Either are OK.  Going to either of these will allow you to use the unicast rotors that are a one piece hub/rotor assembly.  Good to see that NAPA has a quality piece for this.  The Wagner rotors that had been mfg in the USA come from China now.  As stated, if you have 14 inch wheels then you will have to use the 10.87 inch rotors.  If you go to 15 inch wheels then you can use the 11.75 inch rotors.  Calipers for the E-bodys were the pin type.  All others were the slider type.  Both are fine but the caliper adapter is specific to either slider or pin type and to the rotor size.  My experience has been that it's easy to find caliper adapters for the 10.87 inch rotor and the slider type caliper.  It has been stated here that quality brake pads are not available for the pin type but are available for the slider type.  Your master should be fine.  Note that if you need a new one, NAPA has a real good one that became available a couple of years ago that fits the 69 and is for disc.  Boosters for the original power disc brake were Bendix 8 inch dual diaphram.  They are not available from anywhere to my knowledge.  Other non correct boosters will work fine---just won't be what was supplied originally.  A brake hose has been specified for this setup but I don't remember what the part number is.  Calipers need to be mounted to the rear to clear the sway bar on the 69.  Almost forgot---going to the later spindles, whether 73-76 or the J body, etc, use the larger wheel bearing and that is why you can use the later unicast rotors.

As long as your changing from disc to disc , nothing under hood needs changed
I did a similar conversion on a 1969 B-body a few years ago. my customer bought everything new from Right Stuff ( it was all new - but A-body pieces )

The problem I had was the caliper hose, I couldn't find one I was happy with that provided adequete tire - suspension clearence during jounce and rebound.

I moved the hose to frame bracket thats welded on the frame rail to the front, and made new steel lines to accomodate the changes

Just an FYI; for those looking for 11.75" rotor for pin type napa lists p#4885579 and interestingly shows application for the following vehicles only:
78 fury
80-81 gran fury
75-76 coronet
77-78 monaco
76-78 charger
79 magnum
76-79 cordoba "edit"

p#4885563 is the 11.75" slider type shown available on: (I believe this is the c-body type as it is a little deeper and 1.25" thick)
75-76 monaco
75-77 gran fury (I am sure there is other apps)

and of course p#4885566 is the 10.97" pin type

[HOTROD]

I put 79 magnum rotors, calipers and spindals on my 68 - used the balljoint from the 68 (lower) and moved the brake hose braket -running all new lines -my drums were just wasted  !
Sounds like you are going in the right direction
