Thanks for the suggestion, I think additional support would be helpful.

I played around this evening with the bedframe and added a piece of angle iron bent at one edge to help mate the two misaligned pieces back together. I also added a piece of flat steel underneath the damaged glide, and another angle bracket to act as a stop so it can't be pulled out too far. The result is amuch more stable unit, but if anyone knows where to get a replacement glide, or how to fix it properly, please let me know!
