I believe they will but 67's are notorious for having one-year only part. I wouldn't recommend backdating a 69. If anything, newer is usually better in this series.
Front (and rear) brake drum assemblies on a '67 F100 will be narrower (smaller) than those on a '68-'72 F100.
If you're going to be swapping front suspension/brake components out, it would be much better to swap in the front suspension and front disc brakes from a '73-'79 F100/'75-'79 F150.
I replaced all the front suspension/front drums on my '69 F100 Ranger with the suspension/front discs from a '77 F100 -- MUCH better than the drums that were on my truck.
