Changing front bumpers and guards between 3rd Gen

Howdy Team,
Are front bumpers and grill guards interchangeable among 3rd Gen models?
Are stock front and rear bumper caps/covers and overfenders/fender flares interchangeable among 3rd Gen models?
What about the other similarly aged vehicles based on the Tacoma frame?

Mostly asking because I will be hunting craigslist and the like to purchase these components used. For instance a Landcruiser and a Taco '17 had bull bars I wanted and the 17 also had the bumper covers.

Thanks all.

PS I can't get off this site...so awesome.

What about the other similarly aged vehicles based on the Tacoma frame? I don't think so.

 

Good stuff, thanks for the head start!
I'm wondering how far back they are reverse compatible. 2015 Brush/Bull Guard go on a 16?
TIA
