Will this mirror bolt directly to my car without drilling?

Yes—this mirror uses factory mounting points on the door. No modifications or additional holes needed.

Does this come with the gasket or seal?

Mirror assembly only. Pick up a door-to-mirror gasket separately if yours is damaged or missing—it's a cheap way to keep water out.

Can I restore the chrome or polish it if it's dull?

Chrome can be polished or rechromed by a professional plater. If you're going that route, test a small area first to confirm adhesion to the base material.
