'67 Dart dash frame in a '67 Barracuda

It's a non A/C car, but I have everything from a '66 383, plus the inner dash A/C box from a '70 Dart and 2 sets of under dash vents. I still have to get other odds and ends.
I'm located near Beaumont, Texas.
The evaporator box motor is bigger in an AC car. The hole in the firewall is a lot larger than a non AC car.
