I have 3 windows that have a left and right opening window

Hello, thank you for posting,

Unfortunately we do not have an exact match for the lock shown. The closest we can provide are styles like the 38-001 and 38-078, but we cannot guarantee they will work with your window. 

For the operator, are you able to provide a picture of the end of the arm and the distance between the installation holes from center to center? Thank you! 

Thank you,

We do not have an exact match for the operator, but start by taking a look to see if you could use the 39-353 and 39-354 style. I have related the compatible tracks on the page for your review. 

We cannot guarantee these parts and the 38-078 lock will be a direct fit, but if you would like to give them a try, our return policy can be viewed here. 

Let me know if you have any additional questions! 

We do carry the 39-344 and 39-358 Fenestra operators, but they do not have the same 4-1/8" installation hole spacing as provided. 

Please let me know if you have any additional questions.

With a 4-1/4" hole spacing, the 39-344 and 39-358 are the closest we can provide to your original. Your originals are no longer made. Compare all dimensions and let me know if you have any additional questions.
