Searching for I'm looking for side stop window and side spring lack

For the tilt latch, please start by reviewing the style of the 26-243 and 26-244. Compare the overall dimensions to your original to determine a good fit! 

Unfortunately we are not able to provide a suitable replacement for the vent lock shown. I apologize that we cannot assist. Please let us know if you have any additional questions!
