Unfortunatly if you want to keep the 14b the highest match gears you could use are 3.73s. I dont blame you on not wanting to use the Dana 70. I know it is a beef of an axle, but every one I have come across has been a PILE.

I had the same problem when I lifted my 6.5l 96. I wanted 4.56 gears and 35's for wheeling, but that made me tach out at 75 MPH and 16 mpg with propane. She could pull ANYTHING though! Have you consideded a Gear Vendors Overdrive? You could split gears for even better fuel mileage!
