Nice design Terry. I was wondering how I was going to mount my 76 Moke without a removeable grille! (currently using MD's great design which needs a removeable grille)
One thing I have discovered is that the centre of gravity of the vehicle is not straight forward - I made an alteration to the back mounting bracket which makes the car "top heavy" when turned upside down, causing the car to want to "right itself" if you haven't secured either end with a screw. I used the tailgate area (for lack of a better description) exclusively which was a mistake - I probably will change the back mount to use the subframe mounts as I used in the front of the car.
Can't wait to see your final designs!
