My dad heard about an early 80's F100/150 for sale in our area. He is interested in taking a look at it, but he wanted to know some of the specs and the approx. value of it. It is owned by an elderly woman. It has 40,000 orig. miles. No rust. He was told it has a 300 6 cyl. and they think it is an automatic. It has a yellow and brown two-tone paint job that is original.

Given the information I provided, what trim (Custom, XLT, Ranger XLT) do you think it is? What rear end would it most likely have in it? He is fairly interested in this truck and would also like to know what it might be worth. Thanks!
