Looks like mine is a Baltimore: 3C144B114303
69,XXXX mile truck, Custom, Short, Big Back window, Tinted Glass, Fleet with Dealer Installed Air --- was v8 with Powerglide. The previous owner put it on a '87 4wd frame --- not what I would have done but he did a great job. Still has orig seat cover and 99% rust free.
