Need Heater Box/Core/Blower for 74 Dart 318 Se

I am in need of the full Heater system for a 1974 Dart SE 318 5.2 L I need the box with the core. A blower motor. all the switches. any misc stuff that connects. I may have the controls for dash but if you have all the other stuff I may buy that from you too. I also would like the plastic vents that defrost the front window as I have two but one is in bad shape. I live in the SF Bay area and will pay the correct price for shipping. Right now it seems the heater box is the item i need the most. Thanks SG
