I don't know of any 5-plus ratio ring gear/pinions that are made for a 3-series carrier (4.88 is about the steepest for a 3-series) so you might look up the casting number to see if the housing is a 4- or 3-series.

Still best to count the teeth- that way you can see if it's a posi, the condition of the teeth can be seen, etc.

A word of caution: Be sure to use a W I D E pan to catch the diff lube! It stinks to high hell, and if you get it on the floor of the shop or driveway (let alone on you or your clothes), you'll regret it.
