1974 Plymouth Valiant 4-door slant six, disk brake, A/C, was a low mi driver ... complete part out

The A/C system is already missing the pump and lines, however everything else is still there.|
I also have a 1974 Dodge Dart that has the complete A/C system intact...though it is a V8 car so I am not sure if there is any difference in the pump at all or if they just used different brackets to mount the same pump on the Slant and V8s.
