On another note, Glass (or transparent armor) is going to be your biggest issue. You can add all the opaque armor you want but if you get into a confrontation, the weak point will be the glass. Standard auto-glass does almost nothing against anything larger than a .22LR, and even that can penetrate the windshield at the right angle or distance.
Unless you can find a company that already has the engineering done to integrate on your specific vehicle, the cheaper option will probably be to find a previously armored vehicle, like those posted above.
I'm not sure if they are still around, but this company - The Armour Group, is here in Florida. One of our production engineers used to work for them and worked up the kit on this 80 series for marketing purposes. They may have a kit for a 100 on the side.
