Dodge Trucks....Don Knotts style

When I was a kid my friends dad bought a 1964 dodge D300 cab & chassis, made his own bed and pulled a Cat bull dozer on a big trailer for 20 years.
225 /6, NP435, Dana 60 with 4.88:1 gears. The motor never had any repairs at all except tune ups and a carb rebuild and still ran like a top when he retired.
