Replacement tilt window latch

I am trying to locate this style of tilt locking window latch. The home was built in 1999. Several of the latches have cracked and are not working. I never realized they made so many different types and styles. I only found a name etched on the glass (Guardian) out of Richburg S.C. I would appreciate your help on locating some replacement parts. You can email me or call me
My number is 813-546-4079. My name is Vickie

Thank you,
