Went with the 03-05 style over the 06-07 just because it has always been my favorite style. The first truck I owned that I was proud of was an 04 black silverado crew cab so I'm trying to model this one after that truck.

The reason this works is the 99-06 trucks are all the same generation, they just did a face lift and redesigned the front end basically, so all the parts are direct bolt on apart from the bumper.

Headlight bulbs plug right in, fender liners are the same, and the hood hinges are the same.
