Hi all
Wonder if any1 can shed some light on this, I have small bore shocks and big bore but want to try big bore springs on the small bore
What are every1 using on the small bore shocks to make the big bore springs to fit ?

The big bore spring perches at one end and the big and small bore adjusters together at the other end
