Window locks

Quick Learner from Massachusetts
Hi there. I have very old mastic windows and need to replace the window locks only. I've attached some pictures of the lock and the tilt latches to hopefully pinpoint what size I need. Any help is greatly appreciated. Thank you.

Hi Jenn. Start by looking at our 90-278 Sash Lock. Compare the dimensions below to your existing lock and let me know if it matches up. This replacement doesn't have the rear aligners that your old lock has, but that should not affect its operation. Let me know if you have any other questions.
