There was actually a Service Bulletin, No. T-74, dated Jan. 5, 1955, from the Truck service Department - Dodge Division - Chrysler Corp. that addressed this problem. It reads:
"To all Dodge Truck Direct Dealers and Dealers:
In order to eliminate or reduce propeller shaft vibration, the front of the engine in the Power Wagon has been raised approximately one half inch. This can be accomplished on Power Wagons in the field, that may have drive line vibrations, by installing four plain washers Part No. 120390 between the engine front support plate and the front crossmember on each side".
