I am trying to go from 3.55 gears for my d30/c8.25 to 4.56 with 33" tires. 2000 XJ

The problem I've discovered is that in my newer year XJ, the d30 is low pinion standard rotation and the c8.25 is 29 spline.

All the options I've found, e.g., Yukon kit YGK003, that say they fit this year are actually made for d30 reverse rotation and c8.25 with 27 splines. What do I do?

It's also unclear to me if I will need a new carrier for the d30 going from 3.55?

Update: I ordered a new carrier for the d30 - Spicer 706008X

I am going with Yukon 4.56 gears, part numbers YG D30S-456TJ and YG C8.25-456
