Pictures of the caliper in question:
-Outside of good right caliper
-Inside of broken left caliper
-Outside of broken left caliper (to the left is the front of the car)
Theses are approximate measurements I was able to get with a set of measuring calipers:
-The mounting bolts are 8mm diameter and about 1" long. I do not know the thread.
-The plate on the caliper that the bolt screws into is .37" thick.
-The center of the upper mounting hole on the caliper is 2.4" from the center of the knuckle/rotor and just over an inch from the outer edge of the rotor.
-The center of the lower mounting hole on the caliper is 2.6" from the center of the knuckle/rotor and just under an inch from the outer edge of the rotor.
-The two holes are spaced 2.7" apart.
