Also, I am pretty sure it has a Dana 300 t-case based on the pattern: 4low in front and N, 2high, 4high in the back. Does that make sense? Does that make a difference in fluid type or amount?

I initially went with 90W gear oil when I first swapped a T5 in my '81 because that's what I always thought went in a manual transmission. It worked okay, but shifting was not the best.

When I went to change the oil, I read in a manual for an '84 that came with a T5 that the recommended fluid is ATF.

I tried it, and shifting improved considerably.

After much research ( on this site and others ) , I ended up using NAPA GL4 (part number # SL24239 ) in my SR4 which is basically the same as the T4. Its been in for several years with no problems. Supposedly safe for the brass/bronze parts.

Um... I wish I would have known that. Thanks for the info, I'll put that on the top of my list of things to do.
