I will see it tomorrow when I go. The rear end of the body is being modified to look like an A1C and the rear seat moved forward to give more storage space at the back. The rear seat will be modified to form the lid of a box that will span the width of the Jeep, the box will be used for storage and to keep things dry, the water would have to get up to near the top of the rear fenders before it can get in. The box will be removable, it will be slotted into an additional set of rear seat sockets on the sides on the rear fenders and held in place with a split pin. The bottom of the box will be held down with hood catches.
At the rear of the jeep where the original rear seat was located a cage will be installed to carry cables, ropes strops etc as well as spare fuel cans and any other tools that may be needed including the spare wheel however this may change. Again this will be removable located into the original rear seat sockets on the rear fenders and extending out the back of the jeep as far as the outer edge of the bumperettes and extending sideways as far as possible to sit on top of the rear bumperettes, most of the weight will be taken by the jeep floor. Again this will be held down by hood catches.
The roll cage will extend from the front at the windshield back to the antenna mounts, it will be supported vertically in the middle by one or two supports just behind the front seats this will also allow places for attaching items that need ready access from the front without having to dig in the rear, also it will allow open access to the inside of the jeep from the sides without any uprights getting in the way.
That's how I see it, however practicality of design may dictate otherwise. Now you can all go to town and tear my ideas apart.
It does not hurt to dream as they say 
but here in Vietnam is the one place I believe I can pull it off. Watch this space.
