Thanks for the compliment. The flares are the Bushwacker extend a flare's and I believe they are 1.75". The stock flares do need to come off. I held the flares up to the truck and marked the flares, then used a die grinder to trim them. The rubber trim helps to cover up any small imperfections.
The HID's install pretty easily. The speakers are good and the amp is mounted behind the rear seat on the cab back wall.
Good look with the truck, be sure to post up pictures of it.
