I don't know which section is most appropriate to ask these questions but here goes anyways. Does anybody know which (if any) of the aftermarket disk brake kits for front &/or rear will fit on my Demon with the 14" ralley wheels? I need to know that they fit for sure... all I get from the companies as they have not tried what I'm specifically looking for so they cannot guarantee fitment on 14's.
I could go to the factory disk setup on the front but I don't see a WHOLE bunch of benefit over my drums to make it worth while- correct me if I'm wrong....
I'm installing a Dana rear and changing the bolt pattern in the process (rear to start with) so that's the reason for prompting possible changes on the front as well.
Thanks in advance.

I can tell you that the SSBC front or rear disc set-ups will NOT clear your 14" Rallye wheels, in fact they "just" clear 15" Rallye wheels,...I'd recommend you contact DrDiff (Moparts member) to see if his aftermarket kits are designed to clear 14" rallye wheels

I used the factory m-body 10 inch disc and cleared my 14 inch rims. not ralley's though, so not sure if there is a difference.

you really can't go much bigger.

as for does it matter, 10 inch disc vs 11 inch drums, other than adjustments being easier, unless you race a bit, I would have to say you probably won't notice.
but is a pretty cheap upgrade and once you step up to larger rims you can go with the 11 inch disc.

however I have to ask if you are changing bolt pattern's why not go to 15's? or do you just have lbp 14's sitting around?

I'm not changing the 14" rallyes out as I don't want to deviate from the factory appearance with my 14" polyglas tires. I can change bolt patterns without being noticeable but I'm trying hard to hide the race car behind the factory appearance with 14's. The car does make lots of fast passes and as much as I would like better braking- I'm not willing to change the wheel diameter or style.
I can just order up a new rear drum setup and be done with it, but I figured that being that everything is apart if I am going to make any big changes, now is the time to do it.

then honestly the m-body setup is your best choice. that way you have lbp all the way around.
less upkeep on disc then drum. and easier to get parts later down the road.

So being that you seem to be familiar with the associated swap maybe you can tell me then, do the "M" rotors fit on to the 73 up "A" body disk brake spindles?

Ok- thanks for the help on the front, now just to find out about the rear....

Ok, I'm bringing this thread back from the dead.
Today I went and pulled a front disk brake setup from a 73 dart and when I went to pick up the assemblies I realized that this stuff is a LOT heavier than I anticipated or hoped. It feels heavier than my drum brake setup. I don't know if the majority of the weight is from the disks or the if the calipers are super heavy as well but this seems unacceptable to put this much weight back up front. Soooo what other options are there to still retain the 14" wheel? Wilwood has a kit with 11" disks that MAY clear my wheels depending on how big the calipers are but have aluminum hubs and I have steel wheels- a no-no. I could do Andy F's kit of Wilwood calipers on the factory rotor but if that rotor is as heavy as I think it is, then that doesn't seem like the hot ticket either.
Any other ideas for me?

I did this swap in my 72 Duster. Yeah, it adds weight, but the increase in stopping power is hard to beat. The change to the larger bolt pattern was necessary for me since I swapped in a b body axle.

i used scarebird classic brakes kit with my 14 in rallys.. you buy the bracket from them with the instructions.. then you go to you parts store and buy the parts.. approx 250 to 275 maybe in parts, no ball joints to replace.. just use the proportioning/combo valve for disc and the right MC.. my dart has factory rally's with the sbp.. and i wanted to keep it that way
