Searching for rm-b3000

Take a look at our 23-079 mirror door guide and see if this is the part you're looking for.

Thanks for reaching out to us. This appears to be the same bracket as shown in the photo above. Have you already looked at the 23-079 that we recommended? If not, that would be my first suggestion.

The metal component is unfortunately an obsolete part and not something we can supply, but in my experience it rarely breaks before the plastic bracket. You should be able to reuse it without issue.
