I actually my 73 Scamp had rear mounted calipers. Sure looked to be original and don't know why anyone would have changed them on this car. May have been an early built car, I'd have to check the tag. All of my others 73-up had front mounted.
It wouldn't shock me, but the hoses changed over so they would have been pretty long for rear mounted calipers. People do a lot of weird stuff, so many years later it's hard to know if it was a factory thing or changed by someone else unless you've got the entire history of the car. I'm assuming of course that it was originally a BBP car, and that someone didn't make that swap.
