40 Std Gear ratio

I would pass on any rear end assy"s that were stored outside in the upright position. Water intrusion down the torque tube almost always means bad gear sets.
 
Supereal, what does "spalled" mean. I too would like to swap for a better cruising ratio, economically and easiest to find/install. I have a 36 Touring Sedan.
 
Super is talking about the bottom of the bearing surface on the end of the axel housing where the rear drum/hub bearing contacts and wears away.

"Mechanical spalling occurs at high stress contact points, for example, in a ball bearing. Spalling occurs in preference to brinelling where the maximal shear stress occurs not at the surface, but just below, shearing the spall off"
