Good news! I found a guy who retired from the postal service a few years back. He had bought two postal jeeps and had some miscellaneous parts to a third. Unfortunately he wouldn't just sell me one so I now have two postal jeeps, a motor, transmission, and frame for a third. I'm only interested in keeping one jeep, and will be selling the rest. Now to finish my white jeep so I can get cracking on my postal jeep.
