Need Carefree balance replacement.

Need Carefree balance replacements.
Carefree spring window balance.
Measures 1" wide
x 7/16" thick
x 2 1/4" high

The height may not be all that important

Thanks,
David

I believe I found the correct replacement on your site:
15-218 for the Carefree single hung unit with spring ballast or balance.
