The bottoms of both have rusted through as well as that 'deflecting piece' on the inside. I also messed up the top of the weld nuts a little bit when cutting the brazed joint that connect it to the top center cowl panel. I figured if replaced the panel I could clear out the rust on the inside as well as the remaining rat nest that I couldnt get out with a piece of wire, and then put a fresh coat of paint over everything being that water drains down it.
