F100 Brake swap

I have a 65' F100 with the stock drum brakes, I want to convert the front over to disc. I have been told that you can use the brake set up off of a mid 70s F100-F150 if you use from the king pin out but noone has ever been able to tell me what year or years will work. Does anyone know what years will interchange with my I beams, or can I modify the kingpins to make this possible?
Any help would be great.
