Background:

The 8.75" (AKA Eight and Three Quarter") axle was a very durable Rear Axle, mostly used in the full-size cars from the mid fifties until 1974. Unlike the other four Modern Day axles used by Mopar, the 8.75" had a 3rd Member (also referred to as a chunk, Carrier, or Pig) removable from the front of the axle housing -- much like the Ford 9". This 3rd Member grouped the ring gear, pinion gear, and the differential (or spool) as a unit.
