I need new axles

[Bungy L-76]

I vote for a whole new rear. By the time you get done upgrading the 12 bolt, you'll have almost spent enough for a whole new rear.
Call Strange, but don't order a whole bunch of parts. Have them ship you out one of their S-60 rears. Doesn't use as much horsepower as a 9" and is just as strong if not stronger.
