Coil Spring with Pivot for M&I windows

Question

I am looking to replace this part X 6 windows.  I need to know which parts I need to make 12 complete units.  Also, im not sure which weight to purchase for the coil as I cannot tell if it is a 6 or 9 on the side of the coil.  Is there a way to hold the coil to be able to read the stamp on the side correctly?

Hello,

Take a look and compare our 15-180 coil balance shoe that uses the Series 190 coil springs, as well as the list of related items on both product pages. To confirm the stamp weight you need, I'd recommend weighing the window sash and dividing the weight by the number of coils in the window. Thank you!
