I have got a PX (or even better: PY) Peugeot but I'll bet that's not what you're after 😉.
Seriously: I'm the Richard you've bought the bus from and it's stunning. One year only colour BTW 👍
Bit late but 72 rear corners are one year only as they seem to be similar to 73 onwards (same taillights) but 72 has that small bump where the splashpan bolt connects to. Don't know of any supplier of a 72 corner however.
