These are Milgard double hung windows installed in approximately 2002. The first picture is of the lower window part which is still functioning properly. The second picture is the upper window where the piece has cracked. I'm not sure how to identify the proper part I need. Thank You.

Hello! The part you need is called a pivot shoe. The biggest clue you gave me here is that black piece, which is a match for our 15-225 Tamp-R-Lok. This piece is designed to be used with either the 15-231 (natural) or 15-210 (black) pivot shoe. Look these two parts over and let me know what you think.
