riding mower plastic grill repair

I would try to mend this one but not sure about how to go about fixing plastic. Fiberglass is my first thought but you guys may know better than i do so i'm open to any ideas.

or

if anyone has one (MTD mod. #13am670g372) dson't have to be the very same one that is on there now but one that will work just the same.

thanks
