Thanks for your photos. Based on what I see here, you have either our S380-21, S385-21, or S378-21 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.

The top sash guide is unfortunately not something we can supply. I have seen this model before but it is an obsolete part that we've never been able to find a replacement for. I'm very sorry for the inconvenience.
