Front discs on 65 4WD
Ok. After searching, reading, and teaching myself i am still a little confused about how to and where to find aftermarket front discs for my straight axle 65 F100 4x4.
at some point someone added Selectro hubs and I am wondering if this will affect how this conversion is done.
Can someone bee-line me to an afternarket supplier, and how to best do this?
thanks for the insight in advance.

Nobody that I know of made brackets for your truck. Mark used to own Scarebird disc brake conversions not too far from where I live but he retired some years ago when liability insurance got out of hand and he only ever did brackets for 2WD trucks.
The best option you have for disc brakes is to swap to an open‑knuckle Dana 44. This is the only factory‑Ford path to discs on a straight‑axle 4x4. You get factory disc brakes with better steering geometry - tighter turning radius, stronger knuckles, readily available parts, no custom brackets and no machining. This is the route 90% of people take.

this is the answer i needed. Is there a recommended model year(s) that i should look for this axle? Thank you for the information. Appreciate it. Tom

I believe 1976 was first year for disc brakes on F100/150 4WD. They used coil springs, so you'd need to eliminate the coil spring perches and the radius arm wedge mounts and use U-bolts with your leaf springs. By 1977.5 mid-year they changed from the low pinion to high pinion differential. That made the steering geometry change even more so 1976-1977.5 are the easiest possible. Still some challenges but it can be done.
