Not entirely what your doing but maybe some more pointers on the Marbella write-up here:

Your engine side mount will be different of course, and you have the added complication of the 4x4 prop shaft but the prop has some flexibility in it's joints so should not be a problem at all. The 4x4 output flange position again will be set by that back engine mount.
Also for some re-assurance this is all definitely possible as I've seen some marbellas for sale as 4x4's (although some of them may have been using mk1 4x4 stuff which would be literally a bolt on job with no modifications required).
