Bulldawg--yer right on--the only thing is most that armor---when you see armor with those gun ports in it and the two by two holes around the edge it had to be a kit--reason being---all the 3x4 panels had the gun ports just off center--cept--the 3 x 4 foot sheet hung on the outside of the door and that just happened to have that hole just right for the mirror, then there is the hinge system to hang that particular sheet-its cast-so it wasn't "made" in the motor pool and the same with the armored windshield--it also had a cast hinge system, and if thats not enough just try and imagine that all those trans units just happen to make em all the same---but some trucks had regular steel sheets scounged up as you say and as for the weapons yer right on again, steal, beg, and barter, even build guns out of old parts that were being back hauled to property disposal, later on though we got what we needed, I was on Match Box in 70 and by that time we got what we had to have---also---alot of trucks were single walled, the trucks we had at the 523rd were all double walled------Driver
