It's actually 5-3/8 revolution. Your ratio is 5.38:1

Someone else might chime in but the front is either a D25 or D27 and the back is a D41.

Finding any new gear sets for Dana 41 is near impossible. Finding one other then 5.38 is impossible. While a few ford pickups used the Dana 41 and they did use a couple of other ratios. Those have been long ago used up.
 
Your best option for taller gears is to use an Overdrive or switch to a Dana 44 axle.

FYI next time you have the pumpkin cover off on the ring gear is stamped number like 47/11, divide the 47 by 11 = 5.38.  all ring gear are marked in this way

47 teeth on ring gear
11 teeth on the pinion gear

How do you get 47/11 = 5.38...it should be 4.27.  43/8 = 5.38.
