Hi, Steve. We have a bunch of coil springs like this but I don't know what to recommend based on this picture alone. Can you show me a picture of the pivot shoe to which it attaches? Can you also tell me how thick the spring is?

spring width is 1/2 inch. i have both double and single spring needs. ill weigh the windows for proper tension ratings.

Thanks, that's perfect. Looks like you have a 15-177 pivot shoe, which means the spring itself is our Series 152.
