I just did my fender emblems ( running horse ) and changed the barrel nuts on the F O R D letters on the hood, the letters were loose. I wrapped electrical tape on the smallest flat screw driver i have. I put an old white sheet on the floor and under the hood, because of course i dropped the tiny barrel nuts a few times. Much easier to find them. VERY carefully place the screw driver under a corner of the the emblem where the old pins are, and lift a little bit at a time. Then move to the next old pin. Before you try and reinstall the new barrel nuts make sure your old ones are completely out.(you may not need to take the old ones out )
Good time to wax the area before installation.
