4. You can see from the bumps in the lid which chamber is larger. The chamber nearest the mounting face is for the front disc brakes (larger chamber). This chamber can also be used for front drum brakes by retaining the residual check valve for that chamber.

5. Adapters shown on the end of the two brake lines (and in the outlet ports) will be needed, since the ports are larger than the 3/8-24 brake line fitting. The right port is 1/2-20 thread, while the left port is 7/16-24.

6. Before '68, the residual check valve was in the cylinder bore,
and disassembly was required for its removal. Since '68, the check valves (two assemblies at bottom of photo) are in the outlet ports behind the visible (brass) inverted flare seats for the brake lines, and can easily be removed with a small screw, shown in one of the inverted brass flares.
