wondering where to look for things like bezels, switches, retainers for the power windows and locks, all that sort of things

 

The salvage. LMC Truck has some of it, as do others like Jeff's Bronco Graveyard, but it is pricey. And, you might post here what you are looking for as some of the members might have a few of the bits. They can contact you via PM to discuss price.

 

Thanks, I'll note LMC and Jeff's.
Salvage yards in my area about all crushed anything over six years old when steel was high. Fifteen years ago I had dozens of places to look. Even back into the '40s.
There a lot of small things that need fixing, top of my head; window switch falls out, lock switch nonfunctional, lock actuator nonfunctional, visors flop around etc.
Some of my issues are probably covered in existing threads but man there are a lot of threads to look at.
