Draw out the cut line! Lay down some masking tape first if you're not going to repaint after the cut. This also makes it easier to see the line.
If you want it symmetrical, make a paper pattern for each side (mark one side and flip it over for the other side). Try to use the bolt holes as a measuring point to match up the sides.
