Has anyone tried removing the three dummy switches/blanks to the right of the hazard switch? I want to retrofit my garage door opener to one of them but can't figure out how to get them out. I managed to pop the blank cover off one of them, breaking tiny plastic tabs in the process; had to use hot glue to get it to go back on! Ugh. Waiting to remove the full assembly to see what's behind it and how it's constructed. Any ideas out there??
