Hate to drag this thread back from the dead, but im currently doing this swap on my z with a 2.8 m52. Got a friend building the mounts now off the drawings you posted, was wondering if you had anything on the revised trans mount pictured later in the thread using bmw trans bushings. Seems simple enough to fab up but shop space is limited at my buddys shop so anything i can get fabbed off of drawings helps me keep the project moving while i wait.
Either way this is an great build and cant say thanks enough for sharing those drawings with the community.
