Si montón Window Balance Assembly and Tilt Latch

Hi there!

Thank you for reaching out to us. My recommendation is the 15-259 pivot shoe and Series 159 coil springs. I know it's a different design but it will still work for you. See the video below on the process. 

It looks like your window track already has cutouts so you should be able to remove your old hardware without any tools. 

For the tilt latch, see if the specifications of the 26-243 and 26-244 match up with yours.

You can try widening the cutouts a little more with a utility knife. See the video below for more information. 

The 75-069 jamb spread set is something we sell but we usually recommend them for contractors who do repairs often since they're pricey and can't be returned. 

The part you're referring to is called a pivot bar and reminds me of the 26-336. Note, this Simonton pivot bar isn't compatible with the 15-259 so you would need to purchase the 26-083.
