Front valance

While removing the front end parts on a 65 Barracuda, The passenger side was unbolted and removed. The drivers side has the valance welded to the front. I should use a grinder to remove the weld and replace the valance, is that the correct method.
Also the valance has several holes in it. Where could I find a replacement for this. Getting ready to paint soon, so would like to take care of this step before hand.
Thanks
