Maybe this drawing can help us solve the problem: 
  
  The part we are talking about is the grille. Right? 
If I have understood you right Randy, you are wondering if 
the edge around the grille also is supposed to have black paint. 
Right? As all of us can see on Dave´s scan above, 
it seems to be some sort of thin "chrome stripe" around the grille. 
Are there any ´72-´74 owners out there who can help us?  
(I am sorry, but I can´t help more than this. 
I have been on vacation. That is why I haven´t answered your question earlier, 
Randy.)
