Decided to leave the front hubs as is and put in a lower number rear end like maybe a 3.73. I read somewhere that a rear axle from a 1967 - 1973 3/4 ton would fit. Anything newer than that work?

I have been looking for a 67-72 eaton 4:10. The front section, 3rd member will bolt right in.
If you find out anything else, please let me know.

It's almost exactly the same width drum to drum. It rquires having the drive shaft shortened and the yoke changed to mate up to the pinion and spring perches welded on. The one I found has 3.73 gearing.
