I had a 64 A100. I bought it off the original owner for $500 back in 1989. It had the original paint that was baby blue and white. Window van. Slant 6 with 3 on the tree. I painted the van flat black with blue scallops. I also painted all the rear windows to black out the interior. (I carried a lot of tools and spare parts and didn't want prying eyes looking in) I used the van primarily as a tow vehicle for our race car. A full tube chassis small block Chevette. Between the van and the Chevette, it drew a massive amount of attention anywhere we went.
The commercial version was called Tradesman. The proper backup lights are flat. I added OEM cruise control & electronic ignition to mine ('65) with wrecking yard parts.
I had a 1968 Dodge A108 ... basically a A100 with the long wheel base. Came with a slant six, and was GUTLESS ... 18' from bumper to bumper, all that steel and a flat nose ... it was terrible. I pulled the 6 and put a 318ci small block in it. Engine and trans out of a dodge dart. It flew up mountains at 70 mph, where with the slant six, it creeped at 35 mph with the pedal to the metal. To this day I kicked myself for selling it. About 10 years ago, I bought a 66 A100 pickup ... the slant six tired, so though a shorter wheelbase, still gutless. Currently at a shop, putting a 360 Magnum and 727 in it, and converting the straight axle to disc brakes .... I love driving it, and it should fly now.
