Actually, I picked up the truck from someone who had started it as a project, messed up many things, and was unable to finish it. I've been working on it for a while and still have more to do fixing his mistakes. The only plastic left on it is the radio box. When I got it there was an aftermarket muffler on it. The one that comes off of the rear of the vehicle with 2 pipes. I want to put a stock style muffler on it. I'm just having a hard time finding one made for this engine.
