Howard's or Lunati

Nice '70-74 Dusters are very easy to find. You only need 2 things: Money, and be willing to travel. I could buy one a week every week in 2022 if money and time to go get them wasn't an obstacle.
Here ya go. 12 seconds on the web, 340 so you can forget building the 318, use the money to install aftermarket AC. Done deal. Let us know when you get it home.
