65 dart wheel sizes

You should be able to use a 7" in back with about 4 1/4" backspacing without any trouble. In front you might be able to use the same thing, but I'm not sure. I know that a 14" with that backspacing would hit the upper control arm & possibly the outer tie rod end. I think you'd be safe with a 6" with 3 3/4" backspacing.
