" From: feltonjk@xxxxxxx " " " " " I converted my 70 AMX from drum brakes all the way around to front " disc. I got the rotor from a doner AMC car, but I am not sure which " one. The rotor and caliper etc all fit fine. I replaced the original " 14 x 6 wheels with 15 x 7 magnum 500's. I am using the two spacers " on the front wheels. The problem is that I would really be much more " comfortable with a stud that was a little longer (maybe 1/4"). I do " not have the exact diameter of the stud. It is 7/16" thread. Before " I go any further, has anyone run into this problem? Any advice? that's an unusual stud. every amc i've ever heard of - also mopars and fords - had 1/2-20 studs. only gm used 7/16 afaik. i don't know if it would affect your problem, but amc used 3 different setups in the '70s, and the last one had several variations, including 2 different calipers overlapping 3 different rotors running on 2 different spindles. ________________________________________________________________________ Andrew Hay the genius nature internet rambler is to see what all have seen adh@xxxxxxxxxxxxxxxxx and think what none thought _______________________________________________ AMC-list mailing list AMC-list@xxxxxxxxxxxx http://list.amc-list.com/listinfo.cgi/amc-list-amc-list.com
