I need a Carter 2 Barrell

That's what I need. I want one that is in running condition for a 318. I am putting it on a '72 Duster, but it doesn't matter what year the carb came
off off as long as it works. I don't want to have to mess with re-building it and I don't want to spend a lot. If somebody can help I would appreciate it.
I'm in Spring Hill, Fl. Thanks Larry
