I have several windows that are very difficult to lock because these plastic guides have become brittle and break off. The photos I have attached show the following:
1. Locking Mechanism -- inside view
2. Locking Mechanism Plastic Guide -- this is the part that I need to replace
3. Intact Locking Mechanism Plastic Guide -- closer view
4. Broken Locking Mechanism Plastic Guide
Can you identify a part number for these guides? Thanks for your help with this.
