Does anyone sell new super stock springs?

Super Stock springs have an extra leaf on one side. You can install 2 springs of the same number. either 5 or 6 leaf. ESPO can build you a set in 1 or 2" over stock. These are stock 5 leaf springs I installed 10+ years ago. Still working great! THey were from ESPO.

Cool thanks mike! I was not aware that ss springs had different numbers on each side I thought they where 6 on both. Thanks for the Info!
What would be the purpose of having 5 on one and 6 on the other?
