Certainteed Double Hung /Tilt upper and lower
Thanks for sharing your images with us. Starting off with your pivot shoe, our 15-192 maybe what you need. Confirm our measurements are a match with yours. This part could be used with both the Series 170 and Series 171 coil springs. Look over both springs to see which one would make the better match. Since your stamping does not match with any of ours, we would need for you to get back to us with the weight of your window sash. Moving on to your spring cover, our 15-156 looks a little different but should still work fine in place of what you have. Lastly, for your pivot bars, since your is broken, I can not say for sure whether our 26-353 or 26-175 would make the better options for a replacement. It's best to compare our options with one of yours that is still intact to make the ultimate decision.
Looks like the short tongue, series 170. I stated 15 lbs on sash. Which coil do I need
Here is the broken part of pivot bar. It is on the bottom side of sash
For your coil, our S170-334 if it should be two coils per side. If it's just one coil on each side of the window, then you can go with the S170-408. As for your pivot bars, I would start with taking a look at the parts I previously recommended. If neither one would work, we really would need to see a photo of one that is not damaged at all to make more of an accurate recommendation.
