upper balljoint binding. help!

I got a 98 s10 running 18's up front and after i cut the frame for the lower control arms to go lower the upper balljoints started binding. I read about some people cutting out around the joint then moving it down or getting moog or kaotic balljoints. what would be best way to do it? I need to do something soon before i break a balljoint and so i can lay out. thanks for the help.
