You could use a thick gear set, or rubicon gear set (which is thick). Rubicon lockers are 373 and down offset, but the gears are 410. So, to compensate for the difference, the factory installed thick gear sets into rubi 44's.
Only difference is that the rubi gear uses a larger bolt, meaning a standard carrier would need to have the bolt holes drilled from 3/8 - 7/16 in order to use a rubi gear set.
I just wrote this last week for Aron. Pay attention Al
