My fault totally, just removed to repair, noticed a few threads were folks have butchered their plastics trying to get hinge pins out, easy way of getting them out is a pair of side cutters and a hammer as below, 2-3 nice little taps and their come right out with no fuss, spray a little silicone spray on it first. place side cutter teeth in the recess of pin then tap. My bad if this is already been covered sorry in advance. now to lube up the hinge damper ! Having a day potching around on car and this happens ARRRGH!!!!!!
