Do these bolt to factory mounting points or do I need to drill?

These mount at the factory rocker and rail attachment points — no drilling required. Hand tools and basic fasteners are all you need.

Can I paint these or do they come finished?

They arrive in a primer-ready finish, so you can paint them to match your bed or leave them as-is depending on your preference. Light sanding before primer is recommended for best adhesion.

Are these sold as a pair or do I need to order left and right separately?

Both left and right caps are included in this listing — one order gets you the complete set.
