Was reading the GREAT post for changing coils and points, kinda confused as to using hardened grade 8 bolts in the flywheel puller. if something went bad and stripped out wouldn't it be better for it to be the bolt threads and not the flywheel threads? & if the bolt snapped off in the flywheel I don't think you could drill it out, I'm sure I'm missing something here please set my me straight...:thanks
