Mechanics Hate Us

I have been told that I have to remove the whole panel and replace all three controls which are one unit. this seems like a lot of work for such a small component

I’m currently restoring a 1979 Ford Mustang Hatchback, the car itself is in near mint condition, aside from a few minor repairs, the only major repairs it needs are the rear quarter panels. I was wondering if anyone had some easy repair jobs or better yet, an after market parts catalog that offers the parts in question.
Thanks for you time.

2000 Ford Expedition. Something is loose and the electric door locks dont work. I know there are some hidden clips to take the panel off, hoping you can tell mewhere they are.
