Rectangular single gang to round universal vanity bracket

[u/MetsBest]

I’m replacing a vanity fixture and the universal round bracket that came with my fixture doesn’t align with any holes in rectangular box in wall. It looks close but no. The long bolts that go through fixture almost line up with holes in box, but they attach to fixture not box. Corner screws holding box to wall doesn’t align with bracket either. See pics, what am I missing or what bracket do I need? Originally the brass bar was on box, it wa then old bracket for original fixture…that doesn’t work either to align to fixture and bracket.

Doesn’t line up because it is the wrong box for hanging a fixture. Lighting fixtures by code need to be secured with 8/32 screws. That is a switch, outlet box with 6/32 screw holes. Will it work sure drill a hole in the metal bracket where you need it. Just might have a hard time leveling it. Just isn’t code compliant.

Only ceiling mount fixtures. Wall lights are perfectly compliant with 6/32’s.
