Window lock 1 11/16" long

I've never seen a window lock like this before! It looks very similar to something like, say, our 90-005, but yours only uses one screw that comes into it right in the center.

Do you think you could get the 90-005 to work anyway? It would require drilling new holes, but I don't think we have anything closer.

If not, can you show me a clearer picture of where the lock mounts and what it locks into? If you can, remove the lock from that spot before you take your photo. I just want to see where it goes.
