I only have one answer to your many questions.
In 2006 the Ram was redesigned in the front and interior. In 06 this was the headlights were redesigned and they have this amber strip on the bottom.
In 2007 the headlights were redesigned again removing that strip. They also changed the tail lights to the round ugly one's, in my opinion.
2008 No changes to the truck other than the redesign of the 4.7 V8
If there are any actual dimension changes? I don't know.

I have looked at other trucks that are just like mine and a lot of them don't have that amber strip. I'm trying to find out "why" would it not fit.
I have looked at pictures showing headlights with the amber bar and the ones without(front and back-side of the housing) and I do not see any difference visually. Also, does anyone know why some have that amber strip and some don't. Any help would be greatly appreciated.
