Replacement part

I believe we can help you with this. Beginning with the balance cover, it looks close to our 15-205. It holds three coil springs, like the 3/8" Series 165. Confirm that our springs match up with yours. Your springs should also have a number stamped on the end of the springs. As for the pivot shoe, look over the specifications of the 15-199. We also placed some helpful media guides on this page for more assistance. 

Thank you for replying back to us with more photos and information. After looking at your photos again, I am inclined to lean towards the 15-199 that I previously recommended. Your coil spring doesn't really show us the stamped number we need to determine which replacement coil would work. Are there any other numbers stamped before the "35". If so, could you get back to us with that information? If not, get back to us with the weight of your sash. We'd also like to see photos of an undamaged pivot bar removed from the window, along with measurements. 

For the pivot bar, compare our 26-378 to one of your pivot bars that is not damaged. See if everything matches up. As for the tool you are referring to, our 75-069 jamb spreader tool is the part you're looking for.

Yep, if your window has a cutout then there's no need for jamb spreaders. Jamb spreaders are really just an emergency backup option in case all else fails.

You'll have to unscrew that pivot bar and slide it out of its slot to confirm if it matches ours. 

I'm afraid I have no contacts in your area.
