As Stu said, the A kicker is completely different than all other kickers. A regular kicker is made to slip on to a splined shaft and then a pinch bolt is used to secure it there permanently and the pedal folds in, the A kicker is one piece made to be stored under the seat when not being used. If you have access to a machine shop, you may be able to have a regular kicker machined to fit the A start shaft, but you also have to eliminate the fold up feature because its located on the opposite side and would fold up when you tried to use it. It can be done..........
