I have a very rusty single master cylinder W/O part#
I have power brakes/stock shoe brakes & drums all 4 corners
Help needed for part #

No sure if manual master is different than power

You need a conversion block and a couple lines like this along with a master cylinder for a 1967 (just look up a belvedere or satellite with power drum brakes)
But I'd seriously think about the booster as well. It likely doesn't have much life left.
How about the brake hoses?
Just replace them all in one go.

When I updated my 65 Coronet, I priced a rebuilt single and a 1966 dual MC. The dual was at least 5 dollars less expensive-on Rock Auto. Replumbing is easy. Just cut and flare the rear connection and plug the extra port on the brass block. I think your 66 block is different but, similar.

It's a new project for me/runs great/looks good/just needs some updating & tinkering
I haven't gotten too far except trying to clean up the engine bay
The rubber brake lines look new...however I haven't taken off the drums yet

You don't have a power booster
Is the master the same on manual brakes & power ??

The 66 block takes 1/4" line inlet so it won't work. Remember on dual master front line is for rear brakes back line front brakes. The part number for your single master is on the bottom if it's a factory original.
 
Upgrading is smart......but I just wanted to give you an FYI. You could find that single pot master on RockAuto and other places in the very recent past. I bought a Delco Remy one a long time ago.... maybe a trained eye could spot the diff?? I sure could'nt.

did the 66 satellite come with & without a power booster ????
 
Mine was power brakes,the power booster is a Bendix, 4 wheel drums. Did the conversion to dual master years ago. Have a Bendix that needs a rebuild if your interested $50. Has a couple of broken studs that a rebuilder will fix more pictures if you want

. Booster Dewey is one there are others.
 
IMO, but now would be a good time to upgrade to a dual circuit system.

My 66 was converted during the resto 25 years ago.
Even though my car is a hemi car, I chose safety over dead nuts OE correct

A phone call to one of the brake line suppliers will get you most if not everything you need. Explain to them what you want to d, and they will put something together to make it simple and easy.

I used Finelines but I think they all will get you to the place you need to go.

All the pieces on mine are what is used on a 1967 B body ( master cyl, Lines and prop valve ) and it all bolts in like it was made for it

If you get a new master I would recommend cleaning it down with some alcohol and spray it with some clear engine paint or whatever you have.
Otherwise they get rusty.
