My husband went to a local ranch auction and came home with 2 trucks. I don't mind, I actually think they are WAY cool...but don't tell him that . Anyway, found this place while searching for info on them and decided there was "tons" of info on here that would be helpful. He wants to bob one of them, no plans have been made for the other as of yet. One is a 1970 and the other is 1984, as far as I can tell they are both 818's. Please forgive me if I get any of this wrong, remember I am new
