Yet another brake swap question...

............................
Factory set up. It was new.
The guy I got it from said it was for a 73 Dart but now I'm not sure since I've seen that the caliper should be in the front. The LCAs were used. I sandblasted them and welded the box plates on. I was surprised to see how much slop they took out of the T-bar pivot. T-bars are PST 1.03". Worst part was cutting the UCA bushings out with a sawzall. After 52 years the cam bolts were seized to the bushing inner sleeves.
The factory mounted the calipers in the front, but they can be switched side to side so the caliper mounts to the rear. Guys do it all the time to help with sway bar clearance- it doesn't affect the geometry at all.
