I have 4 plastic mounts for a cabinet tray glide. These mount on the side of the tray to the side walls of cabinet. Do you have 4 of these?

This looks like a drawer slide spacer. Check out our 32-339 1" Spacer to start, as well as the 32-352B 3/4" spacer and 32-334 1-1/4" spacer. See if one of these could work for you.
