Serious need of help!

I agree with Spooler ... not good. Working from the rear of the subframe, would it be possible to use a drill fitted with a bit or a 2" hole saw to drill out the bushing itself so that you could carefully back out the differential with what's left of the bushing still attached (... after removing the front mounting bolts of course)? At least you could then approach the problem with the differential removed from the car. I expect some shop would be able to remove the nut once the differential was out. That said, I'm not sure if there is enough room at the rear-side of the subframe to drill out the bushing. IIRC there's not a lot of space back there.

That is what I was thinking.

Yes, once the diff is out, it probably wouldn't take much effort to hack the bushing apart tp reveal the stub bolt and nut ... which could then be removed with a pair of vice-grips.

This is probably your best bet.

When I put in my polyurethane diff and sub frame bushings I had to remove the muffler(s), rear sway bar and the V shaped brace. With those parts removed, you should have plenty of space to drill around the inner sleeve then use the saw to help cut the bushing around the inner sleeve to aid in differential removal.
