Mark...So far the door will open as original, but will have a section of angle mounted on top, this will act as a lock for the top half of the door. The top half of the door will open up with gas shocks, like the split style on lots of SUV's. I may have to move the Lock and Handle mechanism to the door itself, not sure how much room I'll have/leave behind the gas can rack. The design still needs to be tweeked.
The Exo skeleton will be modular with a front, main/mid and rear sections, for easy replacement. A inner tube section will be welded to the main mid section tube ends, with the front and rear clip sections sliding on and pinned, then bolted to the body mount points.
I've tried really hard to suggest a cab forward element in the look of the Exo and a forward motion with the horizontal lines. Just hope I don't have to change much when I start bending and welding.
