Measured the Chevrolet grille today and confirmed my suspicions that it was for a big truck. The only differences is the frame support and height. The pickup grille is somewhere around 16 1/2 inches high and the larger truck is somewhere around 18 inches. The difference is the spacing, the grille pieces are the same. You can use a large grille for parts and vice-versa. Now if I could only find the original rivets and installation tool...........
