Does anyone have an unworn steering box for an SC Speed 20, or unworn innards, or information leading to new parts (mainly the cam)? This Marles box is not the same as the SA Speed 20, but I think is the same as SB,SD and maybe others. The cam is a shaped/waisted scroll, not a parallel sided scroll.
