Got my Higgins Color Flow totally dismantled now but run into a problem. Even with lots of penetrating oil, I can't get the handle bar bracket to come out of the top fork assembly. Is it supposed to slide up and out? I've been tapping but no movement. Everything was nice and clean to begin with. I don't want to be a 'pest' for you experts, but don't want to damage these parts. Note: the black mark around the piece is from my magic marker. Thanks for any help!
