Hi there, I'm looking for the coil spring mechanism for a bottom double hung vinyl sash.

Thank you

Hello! Please see our 15-087 pivot carrier, Series 180 coil spring, and 16-031 mounting bracket. I am very confident that these are the parts you want but look them over and tell me if you had any questions.

This is great, thank you!

If my sash weighs 13.5 lbs , should I get the 7 lbs coils?

I can try to find any markings on these parts.

Yes, I think that would be perfectly fine. That will give you a total of 14 pounds of support, which is a little over your sash weight, but I don't think that extra half pound will make a difference.
