FYI, if you have a template for the dual exhaust rear valance, you can easily convert a single exhaust valence to a dual exhaust by ink marking to correct cut out, cutting out about 1/8th inch less, then with a small pair of Vise Grips, CAREFULLY turning out the extra 1/8" to final dimension in small increments. Been there, done that, cannot tell the difference when completed UNLESS looking for original part number on the valence. I made my cardboard template from an original dual exhaust valence.
