Just seen Dr S has removed a bonded crown from some SID's and replaced with a clamp-on crown...
Windwave wanted £120 for the parts and £60 to fit them.. is replacing with a clamp crown practical for a novice?
Is it just a case of measuring the diameter of the stanchions (the shiny up and down bits. . not sure if that's the right word for them) and distance apart and matching it up?
