83 d250 9.25 diff upgrade

Ok so its been while since Ive been on here. Finally back to working on my old ram. I have a 440 RV engine with low mileage im swapping out for the anemic 318. Currently has a 9.25 open diff I would prefer to keep the diff and just swap out the innards out for a limited slip for better traction with the 440. I've heard that 83 had some differences in the bearings?
