Milgard balancers

A quick learner from USA says:
I need replacement balancers for a number of windows. Looking at your website, not clear which model to order as one of the ends is a bit different in shape. Please see the pics and let me know if you need additional information. Thanks Dan

Based on your pictures, I would recommend our S390-27 channel balance with a 2640 option. Take a look and see what you think.
