Flat File -- Checking for how to mount some casters

Took all the drawers out to get access to the inner side of the cabinet's bottom surface.  The bottom  is mostly open bu there's a flat surface around the edges of the cabinet that the casters can be mounted to.  It's a little over 2 inches wide but that's just enough for the small casters that I bought for the purpose.



The corner where the caster will be mounted.  There's four spot welds in the area.

Looking at the same corner where the caster will be mounted from inside of the cabinet.  Only two of the spot welds are visible.  There's a closed off box section on the inside that is structural and is the mounting point for the drawer rails.  There's no access to the inside of this box section so a nut & bolt setup will not work.  Will have to use a large sheet metal screw for two of the holes.
This is a picture showing the box structure that completely closes in the corner area. 

The caster needs to have about a 1/2" spacer so that it can completely rotate.  If it was mounted directly to the flange, the wheel would interfere with the edge that hangs down.  One way to avoid this interference would be to move the caster away from the corner but the hollow center makes this less desirable.  It may be possible to mount the caster this way with just three of the mounting holes but I'm concerned that this would be too weak...
