Hello,
Thanks for reaching out to us! I'm sorry to say that we no longer carry a replacement for the storm window latch you have. We believe it may have been discontinued and that it may no longer be available. My best suggestion would be to check with a local hardware store or glass shop, in your area, to see if they can supply you with a replacement for the latch.
Our sincerest apologies that we cannot be of more help with this repair but please feel free to reach out with any other hardware repair projects you might have!
