Will the dash (ENTIRE dash) swap into a 2003?
I know there are differences in the HVAC vents (05 has less), what is involved in making everything work? Does the entire under dash HVAC box have to be swapped?

 

I don't know but it's an interesting idea. It would probly blow my mine to sit in an 03 with an 05 interior. I wonder who else might notice it.

 

I'm doing it for a color change from the light, Taupe, to the dark slate. I have everything done but the dash itself and the steering wheel.

 

The dash in the 03 and 05 should be the same. Are you sure you're not swapping in a dash from an 06? All dodges I've seen from 03-09 have 4 vents in the dash so I'm not sure why you're saying the 05 dash has more vents. I'm confused.

 

The 03' has two vents above the glove box. One on either side of the pass air bag. The 05 only has one.

 

Well, my internet research indicates that you are correct. My apologies.
