Brand new Auburn Limited Slip, something missing?

Hmmm..............brand new newer open box or open end?




No guarantees........
Chrysler 8 3/4" Diff Service Kit | Auburn Gear Aftermarket

Never open box.

Yes, I found that but couldn't find a partnumber and they doesn't seem to ship to Sweden...
Thought that maybe Summit or Jegs could have the parts I'm looking for but haven't found it.
Is there anyone here that could help me?
Maybe someone that have a broken 542051 (Chrysler 8 3/4 Auburn diff) who can sell the springs and retainer or someone that have the partnumber I'm looking for?
