Rear Independent Suspension? Anyone?

As usual, I've got another one for ya'll. I might be inheriting a 90's model BMW 7-Series & got to thinking:

I wonder how an Independent Rear End (IRE) would fare on an A-Body. I'm sure that the BMW Rear is just a playground for all kinds of compatibility issues, but maybe it...or an IRE from some other vehicle swaps well.

I mean, come on - If 'My Cousin Vinny' had one in what? A '64 Pontiac? then why not one of us?

Once again I axx - UDoneThis?
