Header panel/ headlight mounting panel

Hey, so I bought a 2009 LT with some body damage for a steal. I bought a new headlight assembly but when I was installing it I realize that the headlight mounting panel or header panel was no good. Can anyone point me in the right direction of where to find an affordable or cheap replacement part. I feel like there should be a lot easier for me to find any help would be appreciated also I'm not entirely sure I'm calling this by the right name but it's the part where the white clips would go into that panel to help attach the headlight mine is broken
