The posi carriers are different i believe from 2.77 to 3.08 & from 3.23 to 3.73 or numerically higher.If you only want to change the ring & pinion.Youll have to go with the 3.23 diff.Or change the entire carrier from your 2.77.Everything else should be the same.

all 9-bolt parts have to be used with 9-bolt parts, nothing from a 10bolt will work. the 3.23 is not a stock 9-bolt ratio... the stock 9-bolt ratios are 2.77 3.27 3.45.

crazychuck13, do you have any extra 9 bolt axle shafts? I'm looking for a drivers side axle shaft. Any info would be great.
