1955 Mack B70T tandem axle tractor. 1960 220 Cummins naturally aspirated diesel motor with a 743 block. Starts easily and runs well. Mack 5x2 Duplex (twin stick) transmission. Air brakes that maintain good air pressure. Overall solid truck with good potential for new paint, a good buffing or not. Needs a good home with someone who will use it and give it the attention this old steel deserves. Good Michigan title.
