Before 2001, 14 bolts were used in cab and chassis 4X4s, and D70s were used in the duallies with the wide fenders. The cab and chassis duallies had a narrow rear end where the outside of the outer rear tires were about the same width as a normal single rear wheel rear end. The D70s are wide so that the inner tires will sit in the normal inner fenders with a bed on the truck. Two totally different width rear ends. Which width do you want?
