Your storm window latch I believe is no longer available. Take a look at the 91-010 and the 91-011 latches. You would need to see if it fits into the lift rail in the storm sash. If it does fit then you would need to cut off the "bumps" and file the "nose" so it will latch onto the notch in the main frame. Take a look and see what you think.
