Yeah for that close of a difference I figured there wouldn't be an issue. Didn't realize that was the reason for the shift to 4.10 though. It DOES make sense.Your stock diff gear is 37 x 9 teeth 4.11
80 series stock rear is 41 x 10 teeth 4.10
Aftermarket follow the 80 series convention
They are close enough, they can be run on the same truck (I do this on my FJ62)
