Hello! We do sell these parts, yes. See our 15-111 pivot shoe, Series 160 coil spring (which is also 1/2" thick), and the 15-150D double spring carrier. You mentioned that your old spring is stamped with the number 5, which tells me each spring carries 5 pounds. However the Series 160 is only rated to carry .5 pound increments; for example, 3.5 pounds, 4.5 pounds, 5.5 pounds, etc. Can you confirm the thickness of your spring? Another option is the 3/8" thick Series 165, which has stamps that would make more sense in your case. |

Replacing the windows is definitely not necessary in this case. I think you'll find that just changing the coil balance assembly will save you a huge amount of time and money. Let me know if your measurements come up different from what I described. I'm happy to help with any discrepancies. |
