well do you want to mod the 3800 or leave it stock ???
anyhow the first thing you'll need to do is install the milzy transmision mounts in their places and then build 2 custom engine mounts welded to the subframe on the passenger side, the best way to do this is to use some round tubing and round bushing from energy suspension and some 1/4in plate... after that do all the mechanical stuff and finish by the wiring... it'll be easier that way
