Locker, Rusted Carrier. Interchange parts?

I have a 2004 DCSB 3.4 L with a locker and 4.10 gears. Housing is rusted beyond belief, and I found an open 4.10 3rd member and corresponding carrier to replace it with. I'd like to keep the functionality of the locker though. Anyone have experience swapping out/in comparable carriers?

 

You can do it, but you'd need to modify the non locked housing. Personally I'd buy an Eaton E locker for the new housing and sell the locked 3rd member.

 

I assume the other axle is not elock which mean it's a 8.4 and not an 8" like the elock.

 

Lets see some pictures I have fixed many of those axles .

Be nice to know where you are ?
