Window Coil Replacement

A quick learner from State College, PA says:
I need some help identifying which type if coil I need, to replace both of my broken coils. I think that Series 165 3 lbs is what I need, but wanted to double check. Markings: 35" P 5232208 #3.0

First, confirm the thickness of the coil spring. If it's 1/2" thick, you need the Series 160. If it's 3/8" thick, it's the Series 165. Secondly, in your photos I see a stamp of #9, which would indicate to me that this might be the S160-9 9 lb spring (assuming the spring is 1/2" thick). Finally, for the pivot shoe, see our 15-228. Let me know if these parts seem to match up.
