Does this mount using the original grille attachment points?

Yes, this grille bolts directly to the factory mounting locations. No drilling or frame modification needed.

Will this grille fit without removing the bumper cover?

Grille access typically requires bumper removal or trim panel work depending on your comfort level—check your service manual for the specific procedure for your model year.

Does the finish need any preparation before installation?

The chrome finish ships ready to install. Inspect it upon arrival and clean with a soft cloth before mounting to remove any dust from shipping.
