It's not a parts breakdown image per se, but the 1973 factory service manual has a sectional diagram of the brake system combination valve as shown in the following image:

The service manual has detailed descriptions and testing procedures of the B-body and other models in the "Hydraulic System Control Valves" sub-section of the "Brakes" section. Chrysler did not intend for the valves to be rebuilt, so they did not provide service parts, nor internal service information.
