It would appear no one makes bed side rails specifically for the 67-72 trucks but most offer sets for '73s. I can't imagine the dimensions between the stake pockets on a '73 are a whole lot different than on a 67-72. Some brands come with some amount of adjustment which one would think might allow enough adjustment to allow a set made for a '73 to fit in an earlier truck. More specifically, I'm thinking of the Dee Zee DZ99601 set (short box fleetside).
Has anyone had any luck getting bed side rails onto our trucks? Are there any brands out there ready-made to fit our trucks?

I actually like the Putco Locker and Locker Boss side rails better, but they are crazy expensive compared to the Dee Zee versions.
