I found a guy that has a Dana 70 Dually rear end under his '65 Ford. He says it has 5.38 gears in it. I have a 3/4 ton Dodge Dana 70 rear out of a '90. I heard that they made a carrier style change in the Dana 70's. Does anyone know if the 5.38 gears would be "swappable" into the Dodge housing? And if 5.38s are fairly easy to get for a 60 front?
