Tilt window latches

Question

These are aluminum windows over 20 years old in my condo in Boston. I bought spiral window balances for them from you back in 2012. I need to replace some tilt window latches. I don't know which type I need. Do these pictures help? I can't take the window sash out yet as it is still winter.

Given the design of the latch and age of the window I'm honestly not optimistic that these still exist. I recommend changing your internal latches over to surface mount latches, which is fairly easy but will most likely require drilling new holes for installation. Take a look at the video below for instructions for how to convert the latches. Let us know if you have any questions.
