B. Align a ruler with the edge of the bumper as shown in Fig. 13. Then, extend a line collinear to the edge of the bumper until it intersects
the next edge on the bumper; mark a point on that intersection. Shown as a star on Fig. 14.
Then, measure 1” down that star following the edge of the bumper and mark a point. Shown as a triangle.
c. Using the ruler as a straightedge, connect the triangle to the dot as seen in Figure 15. Then extend the line towards the fog
lamp pocket all the way to the end. This will be the trim line. But first, complete the next step to double check your line is
correct.
d. Measure from the intersection of your trim line and the edge of the fog lamp pocket to the upper edge of that bumper face.
Verify that this measurement is 3.5”. If it is not, then check your measurements and redraw the lines. If the measurement is
correct, then you are ready to cut. See Figure 15
e. Cut across the plastic as straight as possible, carefully using a very sharp knife or cutting tool.
f. Repeat the process on the passenger side.
