Gear Oil in NP205 behind a T-350?

Seems if I search, I get conflicting answers... Is it ok for me to use gear oil in my NP205 behind my TH350?

It is a frankenstein of parts. The NP205 and it's adapter came from a pre-smog truck in the junkyard, I believe it was a 1-ton with a TH350 swapped in. The transmission is a TH350 pulled from a 2WD 70's pickup (don't know the year never saw it) that had a 4WD tailshaft swapped in (bought on ebay) and the rear housing removed to accommodate the t-case and adapter.

The transmission has been freshly rebuilt, the t-case hasn't though, and leaks like hell, which is why I'd rather use gear oil to move it around temporarily. Seems like it would leak less, and it's cheaper to lose.

In my understanding, these two units are ENTIRELY separate from each other... So, is this safe to do?
