Good morning all. This will be my first post on the B-Body Forum. I have a 1964 Plymouth Belvedere 4 Door car.

Poly 318 / 727 Push Button / Manual Brake / Power Steering.

Im interested in converting to a duel chamber master cylinder and brake booster. My car has the single pot with no brake booster.

Id really like to go with a cheap master cylinder from 1967 or something.
I guess my I just need solid information on what I can use for the conversion and what fits/ what doesn't work. I don't really wanna spend 450 bucks on a whole kit but am willing to if I have to.

Welcome to the gang ! My thought is sometimes it ends up costing more doing piece mill work.
Yes a 67 -up drum brake master is fine. My 63 has drums and that is what I used.
As far as booster, maybe someone has one with hardware that they removed making a race car.
Best of luck to you.

I did see some booster, master cylinder combos on Ebay from some company for like 289 bucks. they apparently fit my 64 idk haha its such a pain in the butt. I wish I could manufacture parts for everyone to have !
 
I have some new SSBC stuff (master cylinder, booster etc..) I'd like to get out of my parts stash that I believe would work.
PM me if you're interested and I can take some pictures and send them to you.
 
Please, please! Don't put one of those GM-looking boosters and master cylinder on it. Midland-Ross single diaphragm booster will work. You should get the firewall stiffened plate for it, too. And I think there is some kind of bellcrank linkage needed at the brake pedal, too.

if anything ill just upgrade to the 67 model year duel chamber master and deal with no brake booster. I just wish someone would reproduce a single diaphragm midland ross.
 
I have heard if someone called "Booster Duey" Do a search and see if you can find anything. May have what you need.
