It's a Catch 22; if I jack the rear first, I can't get the jack under the
front crossmember, if I jack the front first the only way to jack the rear
is to get under the diff from the passenger (non-exhaust) side (on an LHD
car).

 

I usually get the car up four jackstands to do work under the car.

I just use a piece of wood that fits across the rear crossmember. I've never
jacked using the diff.

This is really surprising to me.  I have always lifted cars by putting a

specific to Mustangs, but all you have to do is lift a Healey axle housing
(even without the differential) to realize that it's pretty solid.  I can't
believe this is a common problem for all cars, and definitely not for a
Healey.

 

I CAN see that putting all the pressure on the drain plug at the bottom of
the differential housing could be a problem.

 

But, of course, now I'll worry about this the next time I jack up my Healey.
Thanks Bob...  :)

Thought about posting this to shop-talk, but I suspect there's more general
car knowledge here.

I believe my Mustang manual has admonitions against jacking the rear by
placing a floor jack under the rear pumpkin.  I've jacked-up Healeys this
way for years, but the Healey axle housing is a single chunk of iron; the
Mustang probably has thin-wall tubes from the pumpkin to the wheels.
Theoretically, you could bend the thin-wall tubes, but I've done it a few
times with no noticeable issues.

Thoughts from the Illuminati?
