1967 Dodge R/T 440 - 4 wheel drum brakes
I currently have a spring(tension)loaded lid on my master cylinder. I need to replace it and am only finding bolt down style lids.

My 67 Dodge parts manual shows a picture of a spring style lid, but my 67 Dodge service manual shows a bolt down style lid.

Which is correct? Did they use both during 67?

Where should I buy my master cylinder?

As far as I can tell, you can use a Dorman M71258.
Summit racing has them p/n DHB-M71258 for $29.95.
This one is a bolt down type.


Cheers,

The bolt down lid is the correct one for a 1967 with DRUM brakes , the picture you see in the parts manual is probably a DISC master cylinder.

All 67 - 70 B body front drum brake cars used this one.

Cardone Brake Master Cylinder
Part No. 10-1323

Many have had the holes rethreaded to the next bigger size, so you might need adapters to continue to use stock fittings on the lines.

This appears to be for a POWER drum brakes setup. I didn't say in my original post, but I have manual drum brakes front and rear on the car.

Some websites I see says the MC36221 is for power drum brakes and some say it is just designated for drum brakes. Raybestos shows MC36221 good for drum brakes.

Dorman M71258 says it will also work but shows either power or manual drum brakes.


Is there a difference in these units?

I have gotten mixed information from many different suppliers as to what I should be using.

This is not fun anymore:(

see the boot hanging out the back in that picture , that is a manual setup but I am pretty sure the master is the same for power vs. non power .

It is, only difference is the power unit has a teardrop shaped piston retainer held on by a screw on the flange, whereas the manual brake version has a boot assembly bolted on with 2 bolts. The master cylinder itself is the same, just need the boot or piston retainer mounted on the flange for your application.
