I have a 1990 YJ and I am having trouble with mounting the caliper. The torque specs I have found for it says that if its a 1987-1989 the torque should be 25-32. If its a 1990 and newer it should be 132. I had the original 13 mm 12 pt bolts(gold in color, like a hardened bolt), but now have broke 2 of them and I didnt even get to 75 ft. lbs.. Could I have a early 1990 that would have had the lower torqued bolts and how would I know? I dont want to find out what would happens if I go with 100 ft. lbs. less then what it might need.
