I would screw them in except the holes where the screws go have large holes behind them. Am i missing something ?Use the screw holes to attach them. The felt window sweep covers up the screw heads. The proper screws are flat head with a slight conical shape.
Thank you also while on the subject do the window sweeps go on before or after the window is fitted thanks ahead
Does R/T specialties also sell the special Phillips head screws for them?Yes, you are missing the clips (J nuts) that attach to the quarter panels. R/T specialties sells them
