Thanks for your photos. Based on what I see here, you have either our Series 380 or Series 385, depending on the depth of the bottom shoe. That's the only difference between them. I recommend measuring your shoe and referring to our dimensions to confirm the best match.

You mentioned that the length is 23", but the stamp is 2130. With that stamp the metal channel should be only 22". You may want to double check that to be sure. Make sure that you're only measuring the metal channel. Do not include the plastic fittings.
