I have a 1953 Dodge M37 Powerwagon. The motor block number indicates it has a 1952 Desoto 6 cylinder in it, which is apparently a better and stronger motor from what I have read. 4-speed transmission is original, it works and shifts.The engine runs well, but brakes are not working, but were working at the time I purchasedit. The bed is in great shape and the cab has rust, as is to be expected. The hard top is original, but has rust. The serial number is 80251090. The truck needsto be restored, but these are built like tanks-solid
