I have a number of broken/missing window latches for single-hung single-pane windows. I attached pictures. the piece that the latch pivots on is broken (or partially broken) on many of them. It looks a little like
90-182 but definitely does not match. Your picture shows that the "pivot piece (aka pin)" goes the full length of the latch where mine has two separate pivot pins (one at each end). I don't think it would matter if the length is that long but cannot tell if it would even fit into the channel on the window. The length of my window latch is 1 3/4" but since it slides along the full length of the window it could be much longer. The real issue is whether the "pivot pin" would fit into the track and whether the catch would hook onto the bottom window frame. I may buy one or two just to try and would then buy more if they fit.
