I have 40 year-old window channel balances that need to be replaced. There are so many different ends available, I can't tell which ones I need.

Hello,
It looks like you have either our S351, with a 15-002 bottom attachment, or S390, with a 15-001 bottom attachment. Take a look at the image below to determine which balance you'll need.
You'll also need a locate the stamp code on the metal channel to choose the corresponding spring strength option for your replacement balances. Thank you and let us know if you have any other questions or concerns.

Thank you, that looks good. My other question is that some of them are stamped "2220/" and others are stamped "2220 X" I don't see the difference between these.

The 2220 is the part of the stamp that indicates the spring strength. The rest is just manufacturer information that does not indicate the replacement that you need. Just let us know if you need anything else.
