Newbie here starting my 1st A body and need a/c help

I do want to keep all the dash stuff oem if possible. I'll put a new heater core, condensor, and evaporator in it, for that matter I could probably use the same lines, just buy new ones if I'm able to change out the compressor and it accepts them the same way. This car is a 69 Dart gt with a 273 in it, I made a typo earlier. How much was the compressor and bracket, do you have p/n's on them
