Used Tow Truck Parts

I have a 88 k2500 I want to update with some modern pieces. I want to know what is interchangeable? Are mid-90s towing mirrors are interchangeable and expandable mid-90s, air intakes BIT interchangeable? I want to use an air intake collar of my truck, so if anyone knows what parts are interchangeable end model if you like I want to know and thank you

Matt if you go to http://car-part.com/
and select the game you're looking ar it will display all the years it will be a direct replacement and you can sort by year, but you'll need to do for each part. I tried the search only went to 1990.
Good luck!
You can also sort closer and find near you.
