Simon, if you have to go the trouble of paying for an intercom to be installed you may want to look at installing a PS Engineering PAR 200 audio panel it has an top notch IC with an integrated 8.33 com radio , Bluetooth p, monitor mode etc
Edit to add: it's kind of strange that Piper put out a Warrior in the 1960/70's without some kind of intercom or at least wired for one, even base models were pretty well appointed back then, I had a 151 which was built the first year after they stopped making the 140, it was VFR but had a 4 place intercom, even had a wing leveler.
