The 14 bolt will have 3.73 gearing at the highest. If so it would be slightly better for you gas mileage wise but it is nothing you couldn't make up for with taller tires on your Dana60. To check the 14bolt just prop it up and spin one tire around while watching the yoke. the yoke will probably spin four times to one complete tire revolution. Almost all 14bolts had 4.10 gears you had to request 3.73.
