Not much news to report on the ambulance but I am piecing together everything I need for the front disc conversion. I got the basic stuff from aajbrakes but I've run into a little trouble finding the proper dual master cylinder (MC571). Has anyone recently purchased one? So far, I've only found it from Mancini Racing ($110) and Pirate Jack (comes with an underneath adjustable proportioning valve for $185). Trying to search other sites but part of the problem is that "MC571" gets me nowhere, or gets confused with a modern Nissan m/c. And I'm getting conflicting information about which applications this fits - 60-74 B-Body or 73-78 B-Body? (even then, there seem to be a several different ones used).
According to Roger, for use with the RPB8001 booster, specs are
1-1/8" bore
9/16" and 1/2" ports on left side
I believe the Bendix casting number is 2225621
I've got a call back in to Roger but he's not an internet guy sonot sure he's going to be up to date on latest availability of parts.
With Centric going bankrupt, it has thrown a real wrench in the works. I was able to find a good interchange listing for rotors on parts hawk but not for a m/c yet.
thanks

I have used the dual master cylinder that comes in a 81 Imperial along with a Wilwood adjustable proportioning valve on two of my vehicles. One on my 66 Dodge Polara with AAJ front disc conversion and rear drum brakes, and also on my 60 DeSoto Adventurer with 4 wheel disc brakes. Both setups have worked great.
@regisbodnar were those power brake setups?

Yes, however I don't use the vacuum boosters, but have used hydro-boost systems. It really cleans up under the hood getting rid of the bellows stuff.
