Is this the correct unit to put in an 03 Liberty front differential, I have 4:11 ratio? It states: "For use with Dana Model 30 front axle with gear ratio of 3.73 to 5.38" I almost never see 30a listed.

Did anyone here get the JBA Dana 30 front steel differential? It states "You will need a carrier and gears for Dana 30 Short." What is the (size) difference in that Dana 30 unit and the stock model Dana 30a?
