Here's what I did with my '98 Z71 and it was sharp!!!
Just wish I had a picture to show you (don't know how to post it)
-took off all body side molding, chrome trim on fenders, stickers & emblems (I like the plain look)
added:
-Ventshades
-Dark tint
-Color coded wiper cowl
-Color coded bug deflector
-Color coded after market grille
-Moon visor
-Smoothie roll pan
-Gibson Cat back exhaust dual entry out the back with tips
-K & N Filter
-Bedliner
(it could have something to do with a female owning a truck, but I had several compliments on it!!!.)
I just bought an '04 and can't wait to modify it.
One thing about the '04 I don't like is the front end sits lower than the back. Not sure why GM does that, but I feel like I'm riding in a car!
(My '92 & '98 sat level - never had to adjust) First thing I'm going to do is adjust the torsion bars to see if that helps among many other additions.
Hope you have as much fun with your Chevys as I do mine!!!
