Both myaccompany headlights are missing the screws that attach the inner mounting point of the lamp to the radiator support near the grille. Can someone tell me if these are self tapping or straight thread? Is there an insert that goes into the radiator support? Maybe a picture? My SVT has the Mach lamps and they are totally different. The Ford dealer gave me some self tapping screws but they are too small in diameter. Something is missing.... Thanks!
