Columbus Mega Oversize Aero Downtube needed

I am looking for a Columbus mega oversize Aero Downtube - ZONH12670112AF

I managed to ruin the only one I have by trying to put bottle bosses on the skinny side, got a little too hot and distorted the tube. I figured out my mistake and know how to do it properly now, but the tube only seems to be available as a kit and I don’t really want to buy the whole kit again.
