Hi there!
Thanks for reaching out to us. We're happy to help with this. However, we'll need more information to determine what you may have here. Can you show us a photo of the pivot shoe? That will allow us to determine the compatible coil balances.
As for the tilt latch, see if the specifications of the 26-243 and 26-244 match what you're searching for.
Below are some pictures the resting pieces. I have 2 different size windows, the windows on the upper floor are shorter but, the teed sprint coil housing is longer, it is about 4.5inches long.
Thank you! This appears to be the 15-199 pivot shoe that's used with the 1/2" Series 160 and 3/8" Series 165. You'll have to measure the width of your old spring band to confirm. To determine the proper spring weights, you must weigh the window sash on a scale and divide the sash weight by the total number of springs in the window.
I'll be here if you have any questions.
