Replacement parts for Simonton window coil?

Question

Hi - I think I have figured out the other parts I need, but I am not sure on what coil I need for this triple coil replacement. So far, I got the covers (15-205) and the pivot shoe (15-199). On it, the coils says #4.0 35. Does that mean this one:

I assume the 4.0 means four pouns and the 35 is length?
Can you confirm?
Thanks!

Hey MJ. Well done, I agree with your assessment. So long as the coil spring tape is 3/8" wide, then it's the Series 165, and if the spring is stamped #4 then use the S165-4 4 pound spring.
