ok this is for those guys who know model A's front to back. are all model A grille shells the same in size? mine on my 29 2door sedan does not fit just right my hood is on the top fits great and the gap is good, but as the as the hood goes down the side of the grille shell the gap gets really wide toward the bottom. how can one tell they have the right shell and correct hood? you guys have helped me out in the past hoping you can again. thanks
