Yes n no. The GT Escort caliper bolts to my knuckle, it's the one used with the Galant rotor. Escorts use a smaller bolt circle than my car's 4x113 though and a rotor that is thicker across the vents than mine, like the Galant. I read something about a guy checking differences between escort and 323 knuckles, wanting to go with a more standard wheel bearing setup or different half shafts or something. I think he didn't go through with it due to tie rod placement and strut mounting differences. My rotors are 10.2" but Capris also came with a 9.something front.
