A close-up view of the right side torsion bar shows the stock drip marks. Notice how the drip marks really stand out. Also, you can see the tan slash mark on the right side bar. The left side bar (not seen here) has two slash marks.Gibson uses unthinned acrylic enamel for the slashes. He uses a one-inch wide brush, available at any art supply store. Simply match the color to what you find on your original torsion bar. If your color code slashes are missing, the chart on page 42 lists the basic colors.According to technical drawings, the single right hand color code slash mark is approximately 12 inches back from the front of the bar. The double left hand color code slash marks are approximately 10- and 12-inches, respectively, back from the front of the bar.
