Drawer guide, plastic. Odd Replacement-only one like it in kitchen. Pics of yellow guide may have loaded upside down... White plastic appears to be original and in ALL other kitchen drawers. Thinking maybe product code 32-088?

The 32-088 was my first thought, too, even before I read your post. I do think this is your best bet.
