Searching for 91-178

I am looking for a sliding window latch that is 3 7/8 inches long and 3/8" wide.

I found a part number once on your site that was 91-178 but now the site says no results found.

This is for old storm windows

Unfortunately this slide bolt set was discontinued some time ago and is no longer available. There are no known replacements at this time. I apologize for the inconvenience.

Do you know of any other businesses that might provide this part?

Or suggested replacements?

Unfortunately, I do not. Storm window hardware is getting harder and harder to come by, and replacements have to be exact in dimension. Sometimes you can get lucky at a hardware or restoration store that has old screens on hand, but I can't say for certain. I apologize again for the inconvenience.
