Yea I agree, they don’t care much.The problem with these trucks is that the guys "de-milling" them don't care, so you end up with these issues. They're being paid to remove stuff, not to put the truck back to factory.
Do you know where the horns are located? Is it by the wheel wells behind the front bumper. The resources for this car is so limited. Usually I find a blueprint of the car after few google searches but it’s quite opposite for this car.
