Balance Springs for Certainteed

A quick learner from St. Louis says:
Hi, I've attached to photos of the spring balances that have broken. I think the numbers on the short spring are 335 SA. The numbers on the long spring appear to be 405 LK. They're 3/4 inch wide. These 2 springs are stacked on top of each other and attached to the "carrier" into which the bottom right and bottom left of window rides.
Can you suggest an appropriate new part?

Thanks for your question. For the smaller coil, see our S170-335 coil spring. For the longer spring, our S171-405 coil spring should do the trick.
