Hmmm...haven't done enough research on hub/rotor swaps for 8 lug stuff to
know for sure, but I'm not encouraged. Problem with bearing swapping is that
there's a pretty limited range of OD's corresponding to the ID's required
for the stock IH spindles. I pretty much concluded that bearing adapters
were gonna be a requirement.

The 2WD spindles are smaller than you might think. The FA-12 got a bigger
spindle sometime '71-'72-ish, AFAICT the FA-1 spindle was the same '52
through '73. Not sure about K/KB's. The difficulty is that IH used 'odd'
bearing pairs that don't have interchange(using Timken's reference material)
to other makes as pairs.

Prolly have to use adapters. I don't think you'll find stock tapered rollers
that have enough difference between the ID and OD and still fit width-wise.

1200 is a '3/4 ton', with a 6 lug wheel bolt pattern. I know of no parts
that will let you disk swap and retain this bolt pattern. If that's not
an
issue, you need a hub/rotor that can be adapted to your spindle, and a
bracket to mount a caliper to the axle bosses that currently mount your
brake backing plates. I've researched hub/rotors off and on for the 1/2
ton
5 on 4.5" wheel bolt pattern and found nothing that's a bolt on. IH used
a
rather unique combination of inner/outer bearing on both the FA-1 and
FA-12
axles. Given the need to run bearing adapters for both the inner and
outer
bearings, there are quite a few hub/rotors that could be made to work.
The
caliper bracket will likely need to be custom made, a GM car or truck
caliper is easiest to use. There are a number of companies that will do
this
stuff, CH Topping, Master Power, SSBC, etc. Take a peek in the back of a
Street Rodder magazine for the selection.
