Sliding Patio Door Strike plate

A home owner from La Mirada, California says:
I'm trying to find a strike plate that will match or work with the one in the photo. It is a dual point latch. I'm not sure of the maker. I purchased 89-030, but not sure if it will work.

I have seen this keeper before. We unfortunately don't sell a replacement and I don't believe it's even made anymore. I also don't think the 89-030 will work for you, though I'm not 100% sure about that.

Before I recommend anything, can you please show me a photo of the mortise lock itself? I can then check to see if any of our keepers are compatible.
