To head off in a completely different direction...
looking for other trucks that use the 1.688" inside wheel bearing ID; cone part number 26884 which fits the GM I-beam axle spindle

I find International liked them for a number of 2wd (not all) trucks from 69-81

One of several examples from the Timken PDF, actual page #s 318 and 319

1975-1969 FA-12: 1.686" OD knuckle
Cone/Cup (inner) ...... 26884-26823[2]
Cone/Cup (outer) ...... 15100-15245[2]

Or a 2wd 74 Travell all with a 392, I think may use a hub that's close?
Are these IH 2wd with disc brakes I-beam or independent front? I'm thinking independent but not sure, seems I would have noticed by now if they were I-beams...

One problem is they use 1" ID on the outer bearings, which is 0.030" smaller than the GM spindle is. (And some of the IH hubs use just less than 1")

Another problem is rotors may not be available? perhaps GM 4wd front rotors fit somehow? wouldn't that me a mix and match?

I'll look into modifying the IH hub to fit bearings that fit the GM axle, and find rotors that work with the GM calipers and brackets.
Might be a long shot, but worth investigating some more I think. If it works it should make for replaceable rotors.
