Identify Ports on 1967 Mustang M/C

I have a new 1967 Mustang Dual M/C...Manual/Drums. I am replacing my Single M/C...Manual/Drums on my 1955 Ford Customline. The M/C is mounted high on the firewall. Can someone tell me which port on the new M/C goes to the front brakes? The Dual M/C has two bowls the exact same size. But one line is 9/16x18 which will be towards the radiator and the rear port (towards the firewall) is a 1/2x20. If I understand correctly the bowl that goes to the rear has a 10# residual valve built in to keep the rear brake shoes closer to the drums. I would appreciate it if someone could enlighten me on this setup. Thanks

The larger line (front in this instance) will go to the front brakes as the front wheel cylinders piston dia. is larger. If four wheel drum, you will need a 10# residual valve on front and rear.

There is also a brake pressure differential valve used that will give you a brake failure warning lamp if desired.

Update on '67 Mustang M/C

Installed it today (in my 1955 Ford) with the large port (line) to the front and the smaller port (line) to the rear. The M/C is mounted on the firewall high above the wheel cylinders. As far as residual valves....I have been told that the drum/drum/manual M/C's have built in residual valves. They didn't put seperate residual valves in the lines on the 1967 Mustang. Residual Valves are used mostly in under the floor installations where the M/C is below the wheel cylinders. I hooked everything up without residual valves and the brakes work just fine. Nice pedal and you don't have to pump them to get more pedal. It will lock up all 4 wheels on a gravel road evenly. Thanks.....Ron

Correct, but not all and it pays to make sure.

Correct. I gave that illustration to show that they are needed, whether in the outlet ports of the MC or installed inline.

Two pound residual valves are used to prevent fluid drain back to the MC in under floor (above MC calipers/wheel cylinders)) installations. These are in addition to 10# for the drum brake circuit(s).
