My 83 idles nice and cool due to the good radiator and fans but heats up on cruises. I'm sure I'm missing some of the plastic underpinnings.

Does anyone have an exploded diagram or picture showing all the components to the 1983 T/A air dam setup?

And please, keep the discussion 83/84 Firebird only as they are different from the rest of the thirdgens with this area!
