I tried to order the 91-056 and -057 but they're discontinued. Do you have a replacement to recommend? Metal is ok too.

We do carry the 91-054 and 91-051 latches. The measurements are a little different, but they might be close enough to fit your storm frame. I'm sorry that we can't offer the originals anymore.
