1954 Pontiac Starchief

I have a 1954 Pontiac Star Chief with a Flathead Straight 8. I am in the process of getting it back on the road. I am converting the brake master cylinder to a more modern day style rather than the Bendix Treadle Vac system. I have one question when hooking up the master cylinder which port on the master cylinder goes to the front brakes and which is the back brakes.

 

The front chamber is for the front brakes and the rear chamber is for the rear brakes.
