Will this bolt directly to my Cavalier, or do I need brackets?

Mounts at factory attachment points—no brackets or adapters needed. Hand-tighten at the base and you're done.

What fasteners do I use to secure it?

Hardware not included with the mirror assembly. Use the bolts from your original mirror or source M6/M8 hardware to match your vehicle's factory spec.

Can I return this if it doesn't fit?

Test-fit before final installation. Once mounted, fitment issues are on you—verify compatibility with your exact year before committing.
