I’m in the process of swapping front diffs and noticed that my original non ADD diff has bushings on each side opposed to the ADD diff I’m swapping in has needle bearings on each side. Anyone know the reasoning behind this?

I believe the diffs are interchangeable so I don’t think that should be an issue and I’m aware of the ECGS bushing upgrade for the ADD diffs but I’m curious why they are different. Can I buy these bushings and are they worth replacing?
