While an H260 in the rear sounds good, there really are no good gears for it. Best I can tell they go from the high 3.x and low 4.x range on the Patrol straight to the mid 5.x range under box trucks with wheezy little 2.4 liter fours pushing 'em. Bet that's a heavy sucker too, wouldn't want to make my V6 lug that around.

4.625 and 4.88 gears are available for the high-pinion H233B that would be used, both are suitable for pairing with our factory 4.636 and 4.90 ratios respectively. Not aware of anything deeper, but the 4.88/4.90 setup ought to let you run 35" tires without much trouble.
