Are these calipers on correct?

FMJ's are the bent bar cars. Volare, Aspen, Dippy, 5th Ave, etc. You know those rust buckets that clog up the wrecking yards? Most of the car is junk but they do have excellent front disc brakes on them. Starting somewhere around 1980 those cars got rear hung calipers with a rear mounted hard line. That makes them the perfect caliper to use for rear hung applications. The bleeder is at the top, the inlet is at the bottom, etc. The are slider calipers and will work with either 10.78 or 11.75 caliper adapters.

This is such a weird deal. The factory built the right parts for people to use on these swaps yet 90% of the brake swaps I see are screwed up by people using the wrong parts. I never have figured that out. The correct parts are just sitting there in the wrecking yard for people to use but lots of Mopar guys insist on jacking around with the wrong parts.
