did you cut out too much bracing or just the lip to allow more air? I have a modified grill...it will need repainted. I was stripping the paint on it when I decided to go to a custom grille. The bottom of the grille doesn't always stay latched because the tabs break off...mine has seen 150 and never came apart, so I am thinking you cut out too much...anyway, pm me if you are interesed in the modified one...
