Your '90 d35 should be the non c-clip design and is marginally stronger than it's c-clip replacement. I put a built 350 in my '88 YJ and the non c-clip d35 held up pretty well with light wheelin and 33" MT's.
Go for it, and keep your eyes open for stronger axles, like a Waggy d44 front and Isuzu Rodeo rear d44.
