Ive been told that to change the rear gears i need to use a differnet carrier as the carrier has different bolt sizes to the 3.21. I do have another carrier that bolts to the 3.73 but its an open centre and i want to keep the lsd thats already in the diff. Can i use the lsd from the 3.21 and put it in the open carrier? Or is there another way to bolt the 3.73 ring gear to the lsd carrier?
Thanks alot

In my opinion it's will be a waste of time and money to go to 3.73, I would be looking at 4.11 as a starting point depending on tyre size and use,also JK don't have a LSD so not sure where you got your info on that, they are an open diff with BLD (brake lock differentials).
