Does anyone know how to install or if able an 05 classic grille and hood on an 03 model duramax. thanks

Yep did that on mine very easy. Just basically swap them out everything is bolted and attached the same. On mine all i had to do was adjust my hood latch up and adjust the hood bump stops. And all you need is the hood and grille. Oh and this only for 2500 to 2500 swap. Not sure if this will work with 1500 to 2500 swap.

thanks for the info. I figured it would work but ive only had the truck a year so not real familiar with body parts. now i just got to find the right color hood.

I did mine in about a hour real easy to do.
