If it's open, I would go to a junkyard and get the knuckles out from a 71-91 (or later even?) 1/2 ton chevy to start. It will give you the spindle, outer axle shaft (if it's different), caliper brackets, and caliper cores.

Then get a new rotor and either rebuild or replace the calipers, install new pads, new bearings.

Probably something I'm leaving out but that ought to get you close.
If original yet, it should have drum brakes with an open knuckle. One year only for that. I would do as suggested and just find a donor front end from 71 up into the late 70s. I believe it is basically a bolt in procedure. Make sure the gear ratio is the same...
