blazer body work help

[briank]

I am tackling the pass side rocker (inner and outer), kick panel, floor support etc and have got the front portion of the body figured out and have moved to the rear. My front lower bed side is solid but I need to replace the rear pillar, b pillar and rocker box reinforcement. Question is, how can I get the b pillar out without damage to the lower front bedside? I have removed the rocker box reinforcement out but couldnt see up inside good enough to see the rear of the b pillar. Thanks
