I found a really cool truck tonight on old rides.com when I was looking at the 64 to 66 C10s. It is located in Menifee, California which is about an hour from San Diego. I bought a 72 C10 about six months ago, so I am not in a position to buy another one right yet. This one seems like a great one for somebody on the board to go get. I am not affiliated in any way with this truck. Here is the link to the ad:

It is a short wheel base, big back window, factory AC custom cab.
