just curious, if i have a "4" series Moroso type posi unit, if there is a way that i can put 3.55 or 3.73 gear on it? i know they make 4 series gears to fit 3 series carriers, but does anyone make a 3 series gear to fit a 4 series carrier?

Richmond Gear makes a 12-bolt 3.73 gearset that will fit on a 4-series carrier.
