Do these require any drilling or modification to install?

No. These mount at factory attachment points with no drilling needed. Remove the old covers, align the new ones, and bolt them in place using existing holes.

Will these covers look good with my interior color, or do I need to paint them?

They ship ready to install as-is. If you want to match a custom interior color, they accept standard automotive paint—test-fit them first to confirm fit, then prep and paint to your preference.

What if the covers don't fit or I change my mind about the look?

Since they bolt to factory points, they're fully reversible. You can remove them and reinstall your originals without any trace.
