[Haynes, Mark] Yes, Virginia(er,Chuck), We racer guys use stock
fulcrum pins, the trouble is the double thread pitch and relative alignment
of the king pin versus the amount of engineering and fabrication time. We
tend to spend most of our time trying to fix what's broken from the last
race before the next, not finding new ways of 'shooting ourselves in the
foot'
