NEED: Badly broken sharktooth grille piece

I am looking for a piece of a sharktooth grille. All i need is a single, non angled rectangle.

I am pretty good at mold making and casting so I wanted to attempt to create a personal version of the sharktooth grille based off of the actual one. SO i need just one of the rectangles to make a mold of and cast parts.

I need something i can do related to cars while recovering from a torn ACL. HELP ME OUT!

got about 14 grilles one for parts tell me what you need
