Rear end with 3.23s

I must have the strangest luck with the 7 1/4" axle since all of them in 25 years have been a 2.76 except one. I had a 2.93 or some 2.9X series a few years ago. ALL of the cars were automatics, `1964-76, evenly split between slanty and V8s. I've never seen a Sure Grip and certainly never a POSI !
