Tilt window latch

I'm looking for Tilt latches that look just like the one shown in attached picture. They are about 1/8" thick and about 2-3/8" long?? They slide into the top trim piece of the window sash and retained by a little bump that catches a small hole in the trim piece. These where used in replacement windows installed in a doublewide that I'm remodeling. About everyone of the latches have the tips broke off and the lever is missing. Thanks Tom,
