I got my bumper filler panels for my 81 regal. I installed the rear pretty easily and the front I see are dimpled where I need to drill them but I have a slight issue of I have never taken the front end apart of this car. So I have no idea how the grille and front bumper filler panel go together. I can see that the filler panel goes on the outside but the grill won't slide behind it and be moved far enough forward to be flush with everything. It just hits the bumper filler panel. Also I don't even see how the front grill connects to the bumper filler panel. Any help would be great.
