Price for gears?
I thought they had a different spline count but could be wrong, certainly will make my search for 4.10's easier if they don't.
you will be required to drill the carrier to ring bolt holes to 7/16" from 3/8 if your using a non rubi. I know this is true for older models. Message Eddie if you want more info. He knows alot more about this I'm sure
I have a 2012 jk sport? for a 100 i will take them if they fit.
Are you referring to the front or back?
