Gary. To endorse GB's earlier comment this is well reported already on the Forum. The kickstart design remained the same throughout all models and years with minor modification over time. As long as the tooth profile for quadrant and pinion matches (Pointy or Flat), then the kickstart will work. Early A7 Longstroke and Rigid/Plunger bikes have the flat top teeth, which is also found in early S/A bikes. When the pointed teeth profile was introduced, this went onto all model ranges and so this was also used on Plunger bikes to the end of their production. Add to that folks fitted whatever they could get, not necessarily the correct parts for the model year, but as long as the teeth profiles match, you'll be fine.
