Ineed to replace the sash balancers in a metal frames window. I have provided pictures of the sash balancer and a picture of the channel that the balancers go into. I think I need a 16" 351 channel balancer. Am I right? This is the only window of its type in my house so I'm not sure if I need the clips or not...I did not find any when I removed the window! Help.
