Pulling K frame

Day one yesterday went very well. But day 2 today didnt go so well. I got to pulling the UCA bolts got the front one off towards the front of the car. But the rear one wont budge. Ive got the nut off it and starting tapping it and wont move. So I grabbed a bigger hammer and starting tapping it and still wont move. I tried separating the Upper ball joint from the spindle and could get that to move either. Any thoughts?
