Kinco window balance replacements

A handy person from Jacksonville, FL says:
Hello -
I need to purchase a number of new balances for the Kinco windows that were installed in my house back in 2003.

I'm reading a post from someone who had a similar request recently, so I hope I'm providing the information you need to help me identify the balances I need.

My current balances are stamped with '29 6 BSI'. If the information in the other post holds true, would this be Balance Option 2960?
I'm attaching pictures of my top and bottom attachments, along with my sash guide, but I believe they are:
Top Attachment: 19-005
Bottom Attachment: 15-004
Sash Guide: 18-166

I have a few other windows of different sizes to check, but I'm hoping the general 'theme' is the same for all.

Thanks for your assistance!
Take care,

Thanks for posting! Everything you listed appears to be in order. Based on your pictures, I would recommend our S385-30 channel balance with a 2960 option, as well as an 18-166 top sash guide. Just make sure the dimensions all match up, just in case.
