Slides have the words Care Free on them but I don't know if the slide are original.

Hello there!
I'm afraid your storm latches were discontinued and are no longer available but take a look at our 91-054 along with the 95-250 corner key. Look over the dimensions for each and compare them to yours to see if this matches what you need.
