Here's what that radiator cap page referenced in the link states: "A cooling system in proper repair will not suffer under the pressure load it is designed for; go ahead and use the 13 to 16 pound cap the system is designed to use. " 13 refers to non-AC cars; 16 to AC cars. I figured your radiator system was rebuilt, so went with what the Chrysler engineers specified. Use a 12 if that floats the boat for you and the radiator guy.
