That's my donor car as well. Since the OE 330 is close to max potential the diff was by far the biggest "butt dyno" upgrade, if not actual power upgrade. Way more perceived change than headers or exhaust.

I found a donor this summer, but it was just too hot to go wrenching

I even bought the big 50mm crow's foot tool to get the lock ring off!

I really need to do all the bushings on the back end whilst there... not enthusiastic about that though...

Get the lock ring off? You don't have to do anything like that. 3 bolts on the driveshaft giubo and 3 on the subframe, that's all.
Bushings aren't as bad as they seem if you have the right tools.

Hmmm, I thought there was a big 50mm lock ring involved... but maybe not!
I'm going to need to re-watch some videos!

That big nut removes the input flange from the diff, you wouldn't be removing that except to service the diff, I'm assuming you're buying one that works and doesn't leak. You'll just unbolt the flange from the driveshaft giubo.

Now I'm even more motivated!
