Could someone either tell me or direct me to a place where I could find the Rear Axle Ratios used in the various Buick models in the '48 thru '55 style differentials. What I'm looking for in particular is the availability of a ratio between 3.2 and 3.7 , preferably about 3.54 or so. Thanks, Jim

In 1955 the Roadmaster, Super and Century used 3.41 early in the year and 3.36 later in the year. The Special used a 3.58 (referred to as a 3.60). Some Specials with standard transmission used 3.90 (rare).
The late year 55's changed to a ring gear bolted to the carrier in all series ( the early model year units along with prior units had the ring gear riveted to the carrier).
