Tilt in hardware identification

Hello! I have two broken tilt in sash locks. I removed them both (left and right on the same window). There is a part number on the back - 8590. Unfortunately, as they were both broken, I cannot provide an accurate full length on either of the pieces. They measure about 3/4" wide and about 5/16" tall. They are spring loaded and snap into place in these vinyl, double hung windows. I look forward to your response!

Thank you!! Just ordered. Let's keep our fingers crossed!
