I can't, for the life of me, figure out how to do that. I've tried pressing around it to try and get it to lift somehow, I've tried getting a flathead screwdriver underneath to push it out and finally, tried pushing on it, which now seems like a bad idea as the pin just got wedged further in. I've seen a video of a guy drilling the thing out, but I don't have a drill and would rather not drill anyway - I don't plan to reassemble the G5 anywhere, but I'd rather not drill anything anyway
I know this Pony, But you just have to leaver it out with a stanley knife, push the blade into the plastic in the centre of the pin then dig it in and lift it up!!! should be enough for you to get it started then you can just leaver it out. Then make sure you pull the hole pin out of the centre socket, then you've got enough flex in the aluminum to do the same with the socket/pin your left with and make sure you remove this one completely as well. Sorry if this sounds a bit dis-jointed but difficult to explain, without showing you. Find pics included, if you need more help i'll try and recreate it with more pic.
