Call Randy's Ring & Pinion, or Reider Racing. Either should be able to help.
It is very likely that you have a limited-slip diff. I've not yet seen a D80 in one of these trucks that did not have it.

Jack both rear wheels off ground and spin wheel if other wheel turns opposite direction you have open case diff. If both wheels turn same direction you have posi type diff.

his question was not if he has an open type diff but which type, trac-loc or posi-loc
