After a number of conversations it really looks like the GU platform is a better fit. Engine bay is bigger, radiator goes back to copper cross flow and is a heap bigger than the GQ, looking for a 3ltr diesel manual with a blown motor not 2000/2001 as apparently these ran the larger dia diff which won't allow transplanting of the 3.9's with lockers, my suspension should be a direct transfer, approx 4K of Brunswick parts though but that includes radiator shroud, eng mount kit and jig and wiring loom. Will put it thru engineering again, with the will wood brakes and supercharger, hunting for a VASS engineer now
