1) Reinforcment.
2) Upper retainer.

"Boss" (luckinator), you mean the reinforcment. The retainer can be left in with nearly any bumper cover. Without your grille would fit very well either.

So cut yours, use a JDM piece, or throw it away. Just remember that without it the cover will sag a little unless it's fitted to the fenders with extra hardware.

And this is getting silly.
