Murray, The emblems have Two pins on the back with nuts. They are put on the fenders prior to being installed. If the truck has not been worked on (fenders replaced or emblems removed for painting) you will most likely have to remove the fenders to remove the nuts from the back (the '81 & up are easier than the earlier ones), if you want to save the emblem in it's stock, correct form. If someone has worked on the fenders, barrel clips are commonly used to install the emblems, you may try looking through the windows in the inner structure & see the front stud (as to if it has a nut on it) or pry out gently & see if it pulls away from the fender. If you are really just wanting them off, slide a putty knife under it & smack it with a hammer, the pin will break. You will want to weld up the holes (1/4") once the emblem is removed. Good Luck, Lorne
