Nice video. I appreciate the detailed explanation. I have a '69 too and it needs some work on that same passenger side fender. It's been 30-years since I last disassembled a Camaro and I didn't quite remember what was involved - especially if I just want to remove the fender only. Thanks.
I forgot to put the antenna up through the fender when I installed it and I was not able to get the antenna up through again. I had to remove the fender in order to install the antenna. So, no, I could not find a way to install the antenna without pulling the fender.
