It might be a long shot, but since the 606 was put into the G wagen you might be able to find the right mounts. Just make sure the engine is at the correct angle.
Added:
Looking through this guy's photobucket shows the 606 with similar mounts to what you had in there. Maybe you could locate the engine arms that would be unique to the G wagen
