I blew my diff

Ah, nice drumbrakes

Another option would be to drill a hole into the center of the bolt and use some left threaded bolt or similar to get it out. Left threaded bolt will fasten itself into your old bolt by screwing it in counter clockwise and once in fully you can now screw out your oldbolt in the normal manner..

I have a nice set with left threaded bits especially for this, costs me a couple of bucks but well worth it (unless if you only bring your only clockwise turning drill along like I did not that long ago )
