Coil balances

Contractor from Philadelphia
Hi guys. I'm looking for coil balances. Usually there is number stamp on coil. In my case there is letter D. Is there anyway to find out what correct number should I get ?
Thanks

See our 15-177 Pivot Shoe. This shoe uses Series 152 Coil Balances. A spring stamped D translated to a 4 pound spring; thus, see the S152-4 4 pound spring. Let me know if you have further inquiries.
