The center A/C duct is trashed and no amount of patchwork will help it. I'm trying to figure out what to do as I've revamped my system entirely and it blows cold and furiously. The output from the stock box is a rectangular port facing up and I need to adapt this to a rectangular port facing out, but offset slightly to the right side. No reproductions are available as far as I can tell and a used one is going to dilapidate quickly due to the materials used. Any creative thoughts?
