The spider gears are at the shop being machined and matched to the specs of the gears that came with this differential insert. Hoping he'll give me a call later today or tomorrow saying they are ready and I can put my diff back together with some new goodies. Another question however. As I took out the diff pin and the 2 small spider gears a small ring that looks like a really thin lock washer or just a thin circle came out with one of the gears I'm not sure where this goes when reinstalling these. There was no such metal ring on the other side (to my knowledge) so only one side has this litte metal "C"/ring/thin lockwasher? Where does it go when putting it back together? I've been printing out stuff from the service manual dino's sig links too but do not see this listed in the pieces of the differential.
