That's the crux of the problem. If you own a cabin cruiser and it needs a part, you can put in at a marina, and if they don't have it they can probably get it in a day or so. If you own a 60-year-old PV there's nobody you can order a part from, and the guys at the nearest shops have never worked on a car like yours before. I was told by one PV owner that he once had to put his in at a railroad car shop, and the crews were very interested in looking it over because they had never seen one like it.
