I posted two questions yesterday and one hads been answered (thanks). I have a 67-68 3/4 ton chassis with a rear end that is a full floater but has only ten bolts on the diff cover. It doesn't have a removeable third member and doesn't look anything like the eaton pictures. It is very greasy and rusty at the same time so markings are not clear. Anyone want to name this thing so I can figure out whether to keep it or not?
