I took the bar end off to remove the helmet hook and give it to a buddy and to install new grip puppies. Turns out my dog didn't like the puppies and ate one... Anyways I went to put the bar ends back in and it wont screw in... I popped the rubber piece out and I dont see anything in there... I even fished around with a clothes hanger... Any ideas? I can't ride the bike without it because my bark busters are not attached to anything!
