Will this cover line up perfectly with the left side bumper cover?

Yes. This cover is engineered to match the factory seam and gap specs on the passenger side. Both halves are designed to meet at the center with factory-correct alignment.

What fastening method should I use to attach this to the frame?

This cover mounts at factory bumper attachment points. Use the existing hardware holes on your vehicle. If hardware is missing or damaged, reference your truck's service manual for the correct bolt spec and torque value.

Can I paint this chrome cover to match a custom color?

Chrome finish requires media blasting and surface prep before any primer or paint application. Test-fit the cover first to confirm alignment, then sand or blast the chrome away in the work area. Primer and topcoat application follow standard automotive refinishing practices.
