Old rusty squeeze lighter restoration. Got FOOLED on ebay

I bought this rusty vintage Imco safety lighter on ebay. It was sold with the heavy wear and mention that flint needs changing but NO pictures or mention of the destroyed of the screw, which made it impossible for an average person to change it. I’m sure they knew what they were selling to me but I can’t really complain since it made the project much more interesting.

I decided to drill a hole trough. A this point I still tried to hammer is a torx head and unscrew it for one last time but this was useless. I used the torx bit and some other screw driver bit to literally just dog out all the aluminum. It was a slow process. I spent one night just removing the screw. Eventually I got everything out. When using this drilling method it is important to be able to drill
