Hello,
We can supply your replacement balances but it will need to be a custom order since it looks like you may have a type of skinny ribbed balance that uses the 15-230 T-lock shoe shown below. To get started, we'll need to see the stamp on the metal channel to determine the spring strength needed for your replacements.
As for your tilt latch, I would recommend comparing the dimensions of the 26-243 and 26-244 to an intact latch from one of your windows. The top is squared but that is fine as long as the bottom is the same shape. Thank you!
Thanks for getting back to us. We just sent over an order link and price quote for you to review. Take a look and let us know if you need anything else.
The order link includes ten of the channel balances with the spring, pulley system, and 15-230 T-lock shoe attached. The tilt latches are not included in the link but can be added to the same order directly from our website before you check out.
