I can't say for certain on a 69, I do know that prior to 1980, as far as the 1973-1979 trucks were built, the steering was completely different between 2WD and 4WD trucks. The 2WD steering box on my 1977 F150 was a long Pittman shaft, rear steer design, similar to the Bullnose and following models except behind the axle. The 4WD 1978 F250 our BSA camp had, the steering box was located up front with a drag link going back to the top of the left steering knuckle. These trucks had a live front axle for 4WD and twin I-beams on 2WD.
The first item to locate would be the actual steering box and affiliated parts as needed, then the power steering pump and brackets for whichever engine he has in it.
