I bought NOS rear axle bearings with retainers from Fusick about a year ago. PNs on the box are #391741 and GR.5.855. The box contained both the bearing and retainer. I think the axle seals are available new. I got a new pinion seal from either Fusick or Kanter Bro. Used my old o ring cover seal.
What is the tag that denotes limited slip, got a picture? Didn’t know it was available on these diffs.
