My Gear shifter has gotten looser and looser even though the bolt was locked tight. so i figured the shifter either needs replaced or a mod most be done. But when i went down there to remove the bolt the head was missing:confused: So i was forced to cut with a dremel in the middle crack of the lever to get the middle of the bolt out to remove the shifter. But it won't come off!!! its extremely loose but it won't slide off the shifter shaft!! What gives!! Someone please tell me what to do to get it off. I really wanna ride tomorrow!!
