Will all parts from a 2006/2007/2008 truck fit an early 2004? Things like the rear bumper, headlights, tail lights, tow hitch, etc?

 

What do you mean by early 04? Is it a heritage

 

Nope, it is a new shape .

 

Most of the parts will fit. The only thingI know off the top of my head that won't fit is the fog lights are different and therefore the front bumpers are too

 

Was '04 the first year for the 'drop' in the doors at the bottom of the window and the 4 door standard cab? So many things change during a model run there's no way you can say anything will interchange without knowing exactly what the plan is. Plus, you're getting basically no info from the original poster, so that usually means no information by way of answers until we can know more specifics.
