2001 Chrysler Sebring moog ball joint

upper or lower? is this on the coupe or convertible?

SEDAN... it's the upper... my wife hit a pot hole... the ball joint popped right out of the housing and is now in two pieces... and i can't get the ball pin out of the caliper housing... the bottom of the pin has a spot to put a wrench to un losen but it's stripped. I cant get vise grips to losen it they wont catch because of the roundness of the ball joint... what do u suggest to get it off? do i need some kind of pully or jus some kind of un human strength??? lol
