Restore factory ac or go aftermarket

Its a 318 v8 with weiand aluminum intake, not sure if that's going to screw with my compressor mounting as it looks like the heater hose sticks up right where the compressor would go. I need to take some pics anyway and will post them up this evening.

Not sure if the crank pulley is there. I have been spending more time under the dash than under the hood on this one, but I will take a look.

I went back through this thread and I know you're working on a 72 Dart but it would be helpful to know what engine. Is the original A/C system crankshaft pulley still in place?
