Can someone measure an M caliper and an A caliper
and tell me if there is a difference in the distance between
the blue lines in the picture below? I need to find out if
the distance from the caliper mounting holes to the outside
edge of the rotor are different. I know this is a 914 caliper but
it was the easiest one to steal and I know my top line is
in not quite the right place but it should give the right idea..
