okay I have a 1969 rambler wagon 440 w/232-6  factory PS factory Weather eye AC  The car has 4 Wheel Drum Manual brakes.  I would like to add Power brakes with Disc up front.  I see several options available.  my issue is finding the Power Brake Booster for the car.  I need one for core.   I did see that i might be able to get one off the concords?  Any help and information would be greatly appreciated as to were I might get the booster and what cars are inter changeable.

I don't think so.  He needs the single diaphragm unit, plus the bracket and pushrod ("AB" I think), for the 64-69 small cars (Americans/Rogues, same as the SC/Rs).  It took me some time to find everything, and I had the core rebuilt rather than risk an exchange.  Switching to front disc without adding a booster will still be a huge difference.

Nice car!
Quote my issue is finding the Power Break Booster for the car.
You don't necessarily need a booster if you have a strong right leg, but the master cylinder bore size needs to match the calipers used. That is more important than the power assist.

First off, I think that only a small car booster is going to work.  I'm no expert but I believe that it is physically impossible to use any other booster due to the tight shock tower clearance in an American engine bay.  Now to boosters, if you are retrofitting with disc brakes, that disc brake booster is the same one that the SC/R's use and is almost impossible to find.  I walked the face of the earth for years and ended up paying more than I should have for the one I have for my SC/R.  The drum brake power unit used to be available, in fact I think I have a Cardone reman somewhere.  You would also have to get the mounting bracket and the pedal pushrod.  The picture below (posted by another member of his Rogue) is what you are looking for.

This is all assuming you want OEM parts.  If you go third party aftermarket, then you'll have more options.  Just my two cents.

I used a Wilwood disc brake setup.  It works great but it is a manual disc.  With the proper bore size on the master cylinder (can't remember for sure but I think it is 7/8 or 11/16) it is easy peasy on the right leg.  Believe it or not it's actually pleasing to feel the beast stopping with the manual setup.

I think that same single diaphragm booster was used for both drum and disc brakes in the various Americans/Rogues/Ramblers from 64-69.

I'm pretty sure the booster/bracket are unique to the 64-69 American.   I have a booster off a later small body car, but the master is tilted up, and it won't clear the brace that goes to the trunnion towers.  I do have a Wilwood master cylinder on mine (disc/disc), I had to modify the pushrod slightly.
