Is this part still available. My bipass doors don't stay on the track because the plastic piece 4023? doesn't stay in the track because the mail part of the piece breaks.

This guide reminds me of our 23-220. Yours seems to lack the same hook, but I'm not sure if it's because yours broke off or not.
