My memory is a little hazy but I seem to recall that the mounting bolt holes
are slightly different. The top bolt is an M14X1.5X34, part # 211615141A and
the lower is M14X1.5X37, part number 211615143A. If you look carefully at
the casting you will see the difference. One of those bolts has a slightly
larger shoulder that won't fit in the wrong caliper hole.  If the holes are
identical on both calipers you have two of the same side.
