Coil balance

A handy person from Desktop ks says:
I have alliance window with broken coil balance springs. How do you tell how many # they are? There are two springs one is obviously heavier than the other and it has a D stamp on it. The lighter of the two springs has CL on it.

Our Series 152 spring looks like it could work for you. Specifically, I would say our S152-4 for the "D" spring (can hold 4 pounds per spring) and S152-3 for "CL" (can hold 3 pounds per spring). What do you think?
