These 18 Ga. CR steel patch panels and plugs are just what you need when converting any US market 74-76 2002 to Euro bumpers. (or just shaving the front bumper completely)

Large panels cover the big holes for front bumper mounts and the small “slugs” are for smaller mounting holes. (square holes should be “drilled up” with a step bit, to taste.)

For best results, these should be welded in by a paint and body professional.
