What stamps to choose for S351-33 channel balances

I am replacing the channel balances on a few windows in my condo and have a few questions. Four of the channel balances have the 3220 stamp but are all broken. Does that mean maybe the window was too heavy? Should I replace it with a channel balance that has a higher sash weight range or is that normal (they are probably about 10yr old)? Also, I have 2 more channel balances that need to be replaced but the stamp is not listed as an option. It looks like it says 32DS 39. I have attached a picture. What is the best option for replacement? Also, do I need to purchase any other materials in order to replace the channel balances or is everything included with them? Thanks!

I'm not sure exactly what stamps you need. For both the 3220 balances and 32Ds balances, I recommend that you weigh their respective sashes and refer to the chart on our S351-33 store page. Look up your weight and then choose the corresponding option. If your weight is not on the chart, let me know what it is and we can work from there.
If your weight is on the chart, don't go with a heavier or lighter option. It is possible to have a balance that is too strong, which can cause complications with how your window operates.
