If you do decide to switch it to a Cobra differential, a couple things I’d do are use a heavy duty rear cover like a FMS or similar with gusseted mount. I’d use solid aluminum mounts in the front plus I would upgrade the center shafts on the axles. DSS can recommend ones.
I’d also change the hub bearings while it’s apart. There won’t be an better time then when it’s apart.
Just my opinion of course!
