Upper ball joint removal on 2011 AWD?

[NurseBen]

Background on my project, it's a 2011 GMC Savanna AWD that I cut the body off and placed a 1969 c10 on. The frame has been fabricated to fit the '69 body and lowered with a c notch in the rear and drop spindles with djm lowering control arms. My question is I have too much + camber with is normally the other way around with a lowered front end. I did press in some new camber bushings in the upper control arms, but backwards for more - camber. This helped but I'm still slightly on the positive side. Question is can the upper ball joint be pressed out? I have seen a Moog offset upper ball joint that I could turn and give me the needed camber but most companies seem to only sell the complete upper arm. Thank you, Ben.
