Peter,

It would be real nice if the 1955 second series truck radio fit into the 1954/55-1st holes. You might want to ask them again why their charts show 1955-59 (for CHTKM-2 NO STATION PRE-SETS), if the radio also fits the '54/'55-1st holes.

Please let us know if it fits and how well the inverter works.

Tim
