Accu Weld 2300 Wondow with a broken coil balance.

Hi Swisco: I am trying to get directed to the best replacement part. I have an Accu-Weld 2300 window, double hung sash with a broken coil balance, right side, on the bottom sash. I will be ordering and replacing both left and right coils so they match. The bottom sash weighs 15 lbs. The attached pics are essentially the remnants of what I could get out of the vinyl frame. My windows had no manufacturers cut outs so I had to create my own in order to get the part out. The only marking on the broken right side coil balance is the number 8 as shown. As I was taking the parts out of the channel I was surprised to find that it was a double coil balance. Dimensions are as follows: Coil Housing 3.25" X 1.25" X 0.5"; Tilt Footer 1.5" X 1.25" X 0.5". Help!

Hi Emily: Thank you for your response. As I said, the hardware I will be replacing appeared to have two stainless coils despite the 8 lb capacity. Just checking with your expertise to be sure that replacement with a single coil part will be OK?

Hi again Emily: Also I do not see detailed product dimensions for the S-140 8 on the product link you referenced. Can you please direct me to them? Thanks, John
