04 Honda Rubicon rear axle question!!(What others fit?)

So here’s a little intro..

04 Honda Rubicon, 500cc.

Bought it used a few years ago and then over the winter had a bearing die on me. Tore it apart to change the bearing on the rear axle, and noticed it was written in paint marker on the axle tube and hub "Foreman".

That being said, what other rear diffs share parts with the Rubicon of that vintage? Reason I ask, is now I need a rear axle shaft as I spun a hub..Local honda dealer doesn’t have one in stock but can order next day BUT if it’s the wrong one, I’m stuck with some restocking prices, blah blah blah.

Thanks a million guys and gals!
