1981 Eagle wagon transfer case fluid

[Rosehillworks]

We had to rebuild the 900 series tranny in our 1981 eagle wagon. I would like to put it back together and don't know what kind if fluid is best for my transfer case.
Just realized my title says this car is a 1982.

Use Dexron automatic transmission fluid

Dexron 2 (now obsolete) or Dexron 3 (the replacement)

Same fluid for all years although the books show 10W30 for the first two years. New Process, the original tcase manufacturer told them to change it because sludge was building up in the bearings if it wasn't changed often enough..
