How do I replace the door gasket (baffle seal) door bottem?

I have a frigidaire dishwasher model dw1800v1. I've removed the door face but can't figure out how to remove the door gasket (manufacturers baffle seal part # 022.587.154126601). I have already removed the 2 retaining nuts from the face of the part but can't get it out. please help. thanks steve
