I started by replacing engine. Then I put a four link on it and lowered the front. I also installed one piece window kit and rear center fuel cell. A year later, I built a new 6 liter LS with 4l60e transmission. Another year later, I added a pro charger and pulley kit. Last year, I fixed all the body issues and made a custom grill. I’ve done literally all the work on this truck myself and I’m very proud of what I’ve accomplished.
