They are both NP231s. How can I tell if the splines match without taking mine out first?

Yours being a 90 it could be 21 or 23 spline input. The 92 is definately a 23 spline.

If the 90 turns out to be a 21 spline you could swap input gears, but that involves tearing into the transfer case to do so. Not difficult if your a decent wrench.
