I need a sliding door wheel for a door that is almost 18 years old. It says Del Mar Toronto on it and that's the only marking on it. The door is back on it's track so I can't show you what it looks like installed. I can do that if required later. I looked at your parts but there are so many that look similar. I hope you can help.

Thanks for posting. This looks a lot like our 81-268. Carefully compare the dimensions we show to your hardware and see how they match up.
