Packard also used Eaton but the pumps for 53-4 are slightly different and larger than the 55-6. I have no idea if the 55-6 pump bodies are the same as the Chrysler pump you have or if yours might be more similar to Packards earlier model. Eaton made many different style pumps.

As Randy said, Packard raised the pump pressure for the Monroe unit by the addition of an orifice and use of a different spring in the pressure relief valve. Possibly Kanter or Max might have the spring and orifice and those could be swapped or added to that pump.
