You don't need to grind the center bolt off..
it's these little plastic nubs on the end of the middle leaf that attaches it to the main leaf,
grind or file those off..
unbolt the middle bolt(might need vice grips to hold the dowel pin side..don't squeeze it too hard and mess it up), then unbolt it..
slide leaf out.
re bolt the middle bolt/pin back..
and your done:headbang:
