I worked on replacing the part that supports the toe board. I could not order a replacement so I tried to rebuild what I had. Here is a link to a couple of bad pictures, if you have a modem it may load slow. The welds are ugly but will be ground smooth, I still have alittle bit of cleanup to do before installing but I am pleased with the results.
