Will tubular side steps made for a regular cab mount the same on a SuperCab? What I mean are, are the holes in the same location on the frame?

 

I'm not sure, but I doubt they are. The best steps are the factory steps. That seemed to be the opinion of several people here. It was posted sometime back.
My Dodge 2500 4x4 has a set of tube steps & I like them, but they were not cheap.

I don't recall Ford offering anything except the fiberglass step on the later OBS trucks, and those are scarce. I want a tube step (had them on my '07 aftermarket) and would prefer stainless as the black and chrome models rust too quickly.

 

Depend how they mount.
Some mount to the cab mounts, they will not work.
Some mount the the frame, they will work
