Hello!
We threw away our trailer hitch on mistake so we need to replace it. Where can our team buy a new trailer hitch for our robot?? Thank you for reading 
You can make another trailer hitch spacer from 1" steel box tubing from the Home Depot, and you can make another C channel piece from the AndyMark C-Base Frame. If you need more C-Base frame, check here: http://andymark.biz/am-0202.html
