They are melted in place with the tabs. Carefully pop them off and put your lense in place on the new tabs . Remember to scrape the chrome off of the sides of the new tabs/pins. While holding it in place after slipping the metal piece on put drops of JB Quik-set epoxy on the tab over the tab/ pin sticking through. Hold it until it sets up and move on to the next lense. Trying to melt them as they were in place just pops off. The full length of the pin with the chrome scraped off gives it something to grab onto. Just did another one
