Andrew, could you scan and send me the page with the flange thicknesses, or make up a chart of years and thickness, disc or drum brakes? Sounds like I got it backwards, but I got the info from someone else who mentioned that the DISC spindle had the thicker flange for the caliper offset. Doesn't sound right, as the caliper adapter is 3/8" thick itself. Disc spindle flange would seemingly need to be thinner to keep tread from increasing to much.

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

afaik.

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.
