I cannot get the bottom front grill off my svt for nothing.

There are these i guess it's plates on each end of the grill and they are hell to get off. And does someone know if those little clips on the grill will still hold the grill tight after removing them b/c it digs in the fiberglass pretty deep. I am painting the grills chrome, I have already done the top grill and it looks bad a$$. I just hope it doesn't start to peel off in a few months. Any help would be appreciated.
