Carrier Size for lower gears

[bikeboy1010]

Hey,
I have an 86' CJ7 and would like to put lower gears in both differentials, Dana 44 & Dana 30 .
They are geared at 2.72 now.
I would like to install 4.10
Will 4.10 fit the existing carrier or do I have to change them also?
Any help would be great.
Thanks

You're going to need new carriers. I'm regearing myself. Instead of going with a larger carrier and spider gears, I'm installing Truetrac lockers while I'm at it.
