Your three factory options should be 3.73 , 4.10 or 4.56's .
4.10's being the most common but all were availble.

RPO = Regular Production Order They are codes used by GM to identify parts/options.
Example : A "M22" is a RPO for the old close ratio high performance Muncie "Rock Crusher" 4-speed used from 1965 to 1974 in GM cars .
