1968 Barracuda headlight bezel attachment

So before I even attempt to take the headlight bezels out of my 68 Barracuda (to remove some dings) I'm looking to get some tips from someone who has removed them before. As well as maybe an explanation or exploded drawing on how they attach. My car is missing several of the perimeter screws that,it looks like to me,attach the bezels to the fender. Do these screws go thru the bezel & into a hole in lip on fender? Do they have a sleeve they go into?? What do I need for screws??
