I have tried in the past to run down parts to rebuild one but i soon gave up. Good luck.

You could ask for a rebuild kit...I think it's entirely possible too rebuild it yourself. There isnt much to them,but dont take it apart until you have the kit.

I had the 7 inch booster rebuilt by Stewart,s in Stoney Creek,Ontario.This was for my 68 Barracuda and they got the parts(diaphram)from Cali.

If you get to taking it apart,, BE CAREFUL!!!
If memory serves me, there's a loaded spring in there, that'll throw you back, if you're not prepared.. If it's a "twist apart", I put one part in the vise, and drilled holes in a piece of plywood for the mounting holes and centre, then twisted the plywood to disengage the halves..
Definately get a manual, or perhaps some-one can post a link..

Booster Dewey rebuilt the booster for my 1969 340 Swinger - that was in 2000, and he did a great job - thing works great to this day!
Bingo , that's what fiend said , hard to build without the tool . He put out lots of calls ,no luck . have a used one that ""might "" fit , will see tomorrow , what a great bunch of guys at this garage none in quebec one used in Ontario they really searched , this thing is as rare as hens teeth .
Will have to go the boosterdewey or Stewarts in Ontario route when I pull the old one off . What a pain !
One more question did the booster change in 72 up with the single piston caliper ?

I took the Midland-Ross booster (V-band clamp) apart from my 65 C-body. There is no spring that will hurt you and it is very simple inside. My diaphragm had a hole and hard rubber right where the vacuum attaches, so must have gotten gas fumes from the manifold, despite my installing an in-line filter for Mopar boosters. I didn't find any internal parts for sale, other than one input valve on ebay. Maybe Booster Dewey could be talked into selling a kit, but I figured with his rebuild prices, I'm too cheap a date.
I had a Midland-Ross booster from a 74 Dart that looked identical other than the stud spacings on the rear, so thought I'd just swap baseplates. I found the input pistons were different sizes and no way to swap parts to make it work. I ended up drilling new holes in my adapter plate (C-body) for the 74, then swapped it out when I found a correct booster/MC for only $70 on rockauto, though it was the other style (Bendix?, crimped together shell).
Before that, I got the bright idea to rebuild my 65 Booster without parts. I bought a roll of neoprene rubber sheet on ebay and cut a new diaphragm. However, the factory one is molded, so a little hard to make it fit. I forced it into the gap in the two spot-welded plates, w/ superglue and weatherstrip cement to secure it. I tested it under vacuum and it works, but didn't install on my car. It will be interesting to see know how long this Billy-fixed diaphragm will last if I ever install it.

I think it srange that no rebuilt parts are to be found. With the wide variety of parts available this is a gaping hole in the hobby!Some guys LIKE rebuilding thier own parts. Some guys dont trust another to get it right...
Thanks , booster and MC off to John Stuarts , expensive , but at least they can do the job . Will have SS sleeves put in the master , they say 4-6 years for a regular rebuild should last as long as the car with SS sleeves in it .
Thanks again, will be good to have solid brakes again.
Strange is right , is the 1970-1972 340 booster MC different than the 318 booster MC with disc drum setup ? There are so many MC available , but non look exactly like the unit on my car , which is original .
