One of the most visually important parts of kit and custom cars is the grille, since that's the first thing people see. In the 1950s, many custom cars featured grilles with square or rectangular patterns made from flat metal stock, which became known as egg-crate grilles. Many production cars also used similar grilles, including 289 street Cobras, most Ferraris, and the 1965-67 Sting Ray. Custom car builders usually made their own grilles from aluminum bar stock, and they're easy to fab yourself using only a tape measure, a chisel, and a table saw. I made one for my Devin project car, and although the first one was thrown in the scrap bin, I learned enough to not make the same mistakes twice!
