1970 Dart Radio, Heater Panel w/ AC

I need a radio, heater with AC panel for my 70 Dart Swinger. This is the only part that I have not been able to find anywhere for the past 6 months. If someone has one for sale please contact me, or if you know where I can find one. This was the only part in my car that the old owner cut up so bad for a newer radio that I can't fix it. Please help me!!!
