N, check again I drew red lines to make them easier to see.
Again, the stud material is very thin and light (hyper lite) and probably wouldn't hold much weight. I would go with a short #12 to #14 sheet metal screw not self drilling, but would drill a small pilot hole.
Wall thickness you already know about. about 1 inch (MOL)
If the track has to hold substantial weight, I would through-bolt it through the sides with probably stainless carriage bolts, but I wouldn't want to have to do that.
