Help replacing my drawer track back plate

Hello, I am trying to find larger Drawer Track Back Plates. Mine are close to 30 years old. Your 32-089 looks close, but the 3/8" opening should be 7/16". I will attempt to send a picture. My broken one is on the left. The one on the right is a Liberty brand from Home Depot and it is too small. Can you match the one on the left...1" and 7/16" opening. Thank you, John
