Complete AC for slant six

It's early and I don't have the car running yet but I have no doubt that I will. So I am starting to look for an AC unit for my 75 Dart Swinger slant 6. Someone has removed it from the firewall forward. I do not need the heater box. I think the wiring or at least some of it is there but, I need everything else. I hope to find one close to me to save on shipping. Thanks
