Hello there,

You didn't give dimensions, but being in California, you probably need the S385-19 side load balance with a spring strength option of 1820. Compare our dimensions to yours and see if they match up.

I followed your suggestion and they are a perfect match. Just installed and they work great, and a huge improvement over the older balances.

Thanks so much for your help.
