I'm afraid I can't tell what that pin is from these photos. Would it be possible to see it removed from the door?

Thanks for your patience while we looked into this. The best match we were able to find was our 23-115 spring loaded top pivot. I can confirm that it fits the 23-407 corner block, which resembles yours.
