napa says #12/#13 for mustangs including II, pinto, and most other
falcon-derived fords. sounds like these use the same race - inner or
outer - as the amc's #2/#6, if they fit.
" I have a set of 1963 drums that I'm removing the hubs from. Note
that
" drum hubs will fit on disc spindles and rotors on drum spindles,
but the
true of all but the big bendix spindles, which use different
bearings,
afaik.
" mounting surface (where the four holes to bolt the spindle on
are) is a
" bit thicker on disc spindles to space the rotor out for the
caliper. I
" have verified fit of a 1980 concord rotor on a 63 drum spindle,
and vice
" versa.
the mitchell master interchange listed several flange thicknesses
starting in the early '70s, with the drum spindle generally the
thicker to match the caliper adapter behind disk spindles.
