Sometimes these things can really be miserable to get out. Sometimes the paint makes them tight or hard or they will get rust build up in them etc. I have had to (unfortunately) resort to using heat on them sometimes and a large hammer to get them out. The big trick is to try to do so with the least possible damage to paint and adjoining surfaces. If you have to use a torch on them, be sure to protect as much of the painted area as you can. Sometimes you can soak rags in water and cover the area you don't want to get hot. Sorry that your having problems with them, I know how bad they can be sometimes. If you have access to a compressor, sometimes an air hammer will move them easier than a regular hammer, because of the short quick blows they deliver. I wish you luck with them. Also if they are long pins, make sure they do not have a retaining clip on them. Thanks
