I found the part number for the Grass Adapter brackets, but I can not find the Draw Slides that I need.

Thanks for writing in. Take a look at our 32-061 21-5/8" Track or our 32-062 23-5/8" Track. Look them over and see if you could replace your old track with one of these. If you do, I recommend you instead use our 32-018 Drawer Slide Socket pair. See what you think.
