I need to replace to balance spring assemblies for tilt windows. I looked at the three series of parts on the Swisco website for a match, and none seemed to look right, but perhaps one will work. I'd like to provide a description and hopefully you recommend the right part. Here are the characteristics of mine: - there are no plastic shoes at the top or bottom - the channel is a plain channel that is 24" long and 1/2" wide - the spring is 12" long; at the top it is fixed to the channel by a rivet; the bottom has a pulley - a string is connected to the pulley at the bottom of the spring - the string passes through a second pulley that is fixed to a 1" arm that is connected to the bottom of the channel by another rivet - there is a final, third rivet just below the rivet connecting the 1" arm - The string ends is a small hook that is inserted into the shoe (which is separate) Thank you in advance
