We need to replace balances on Simonton 5500 series vinyl replacement windows. We would like to do 1 window first. The coils have no stamp on them. The bottom sash weighs 18.6 #'s.The top sash weighs 17#'s. We have included pictures. Please make a list of the parts needed and we will place the order. Thank you for your help.
