I'm pretty sure that all FMJ body cars had rear hung calipers. It has been 20 years since I was a regular at the wrecking yards but that is what I recall.
according to RockAuto, the calipers are reversible.
If by reversible you mean front mount to rear mount
- Right Front Mount would become a Left Rear Mount and still keep the bleeder upright. That says nothing about the brake hose connection and hose routing.
I used calipers from 1974-80 Monico/Fury/Imperial/Vans/Pickups with the 11.75 rotors and caliper proper tall caliper brackets on my 71 dart. They are front mount and the car does not have a sway bar. Can't remember what brake hose I used but it was a factory one
This article was what I went by:
