Trim levels. 67-72

[Stm3784]

Hi guys
I’m hoping someone can tell me the difference in trim levels. I know base custom CST Cheyenne. But what was on the trucks at various levels. Like I see wood grain, and black trim, but I’ve also seen trucks (69-72) with either the lower wide trim at the bottom, the barrow line up top, or both. How was it determined what got what I’ve been trying to figure it out but kee coming up short. Thanks
