When I said Crossmember, I meant the transmission crossmember that bolts to
the trans and then to the front rubber trans mounts. NOT the suspension

As per suggestions I read here a year or so ago, I removed /installed the
trans with the crossmember attached. I removed the crossmember to body mount
nuts. I also found that the bellhousing to diff bolts were easy to get to
while on the ground. This should settle your mind more when bolting to
aluminum as you said. 
I have never worked on a LM but I understand that there are tricks for
re-attaching the axles. Something like jacking up the A-frames. Others can
most likely chime in here.

     Thanks for the write up.  I actually did remove and install the 
drivetrain in my 65' Corsa once already.... it wasnt all that bad a job but 
I hated bolting that crossmember back to the bottom.. into the aluminum... 
it was hell to get it lined up and I was terrified of damaging the aluminum 
case...  I was hoping to avoid that part.  Also I had a hell of a time 
getting something lined up at the wheel end of the axles... the universals 
maybe?  That would probably have been no trouble at all if I had waited for 
an available helper.. but I was impatient as usual.
