I have been pondering the same thing for years... and not come up with anything that doesn't require a bunch of cutting and fabrication.
Except if you start with an AWD Tempo!!!
Very nice li'l IRS half-shaft set-up.
Except none of my fleet of Tempos is AWD.
Come to think of it, all I'd probably need to get is the rear carrier bearing and half-shaft for one side and it should bolt right in! And it wouldn't need any of the other AWD stuff anyway. Hmmmmm.
I suppose any little AWD car would give a tremendous head start on such a project.
