Joe if your unit is readily available to photograph - please provide pics. It will be at least a week before I can get to my shop. Roger is correct regarding the stud spacing on the master cylinders. I know I have at least one of the single diaphragm units in my parts - but will have to check to see if it’s power drum or disc. It would be a core either way and require rebuilding. |
thanks yes i would buy it from it you. as i understand the drum unit works well with the disc setup just not as much boost and im okay with that. fingers crossed. and everyone thank you your great group of people and spending the time.

yes please that would be great, also as i said my fathering-law is a machinist. if i had drawing or measure meant of bracket we could make one ore even a pencil outline of the bracket. im okay with using aftermarket boosters as well. again thank you |
The OEM bracket is more complicated that just a couple stamped pieces. Here's a photo of both the big car and small car brackets. The lower one is the small car.
As to the booster, this is what it looks like. As I mentioned, I'm sure I have a Cardone reman drum booster if anyone would want me to look but I don't have a spare bracket set. For the anal crowd (of which I am a charter member) there are two versions of this small car booster. The early version has the twist lock style check valve and the later version has the push in style check valve. I know that '69 has the twist lock but that's all.

I found the correct power disc booster for my SC/Rambler at O'Reilly's. The correct bracket will be difficult to find.

I found the listing on O'Reilly's website and called my local store. Said they had to call somebody to determine availability and they'd call me back. That was over eight hours ago and no call back. Not holding out much hope.

i see the bracket and now understand how they are engineered to work if i gout get some measurements the would be a great help and see if we can't come up with something that will work

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 think that same single diaphragm booster was used for both drum and disc brakes in the various Americans/Rogues/Ramblers from 64-69.
|
The booster is the same but the C-C distance for the MC studs is different drum to disc. The disc booster master cylinder mounting studs are
approximately 3 1/4" from stud centerline to stud centerline while
the drum boosters studs are approximately 3 3/8" apart.
|
That pic is my 68 Rogue circa 2003. It is a drum brake booster and I used it for KH disc brakes. I am pretty sure disc brakes had a different booster but I have used a drum booster on several disc cars with great results. I had to egg shape the master cylinder holes a little to make it fit. Of all the cars I have built, that car has brakes that are the most like a new car. A forum member sells the mount assembly for other model cars and it looks just like this one. I have asked several times what the difference is and never got an answer. I had a Jav/AMX booster and it is too long front to back and won’t fit. Some early 1960s Fords had similar looking boosters but I never tried one.
