66 Dart owner help needed

I am going to send out my tailight bezels for rechrome. I have 3 sets of them and non are what I would call nice. I really didnt want to do that but they are just to pitted. My car isnt being built to be a show car so if they were a little dull or had some slight inperfections I would be ok but all 3 sets of mine are pitted to bad for my liking. I do have both, right inner and outer that are good enough but no left matching so I guess its rechrome time. (unless someone wants to make a deal on a swap and some cash!) Anyway I went to disassemble them tonight and the screws that hold the lens to the bezel are so tight I cant get them out and I dont want to round the heads off. So I thought I would ask how others have gotten their screws out and has anyone soaked the entire assembly in a solvent that would help to loosen them wth damaging the lenses? I guess if I have to I can drill the heads off and then remove the stud that is left? I think that the bezel is a pot metal so heat is not a good thing.
Hope someone can give me some ideas.
Thanks Rod
