We should be able to help with this balance, but your photos only show the bottom fitting. In order to help, I will also need to see a clear shot of the top fitting. Please let me know if that's possible.

Perfect, thanks! Based on what I see here, you have either our S380-21 or S385-21, 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.
