68/9 dart door panel emblems

I have the pair of these. Still attached to door panels. Looks like they spun the rivets (posts) to attach them. I am not sure how to remove them from the panel and save the posts. Any ideas?

If the panels are in nice condition PLEASE don't cut them up. The emblems are held on by 2 studs that have a tiny washer and are peened down. To remove them you just need to very carefully removed the peened down material. When reinstalling them: the washers go over the studs and then a drop of 5 minute epoxy. Done it many times.
