Because I didn't include it. Do it however you want. I know the way I've been setting them up almost 40 years works. One more time. This is all covered in the MP chassis and suspension book. Just like all the engine information is in the engine books. I never have understood why some Mopar guys refuse to get copies of those books. They were the first publications I bought when I got serious into Mopar. It seems like some guys dig their heels in even harder against getting them whenever some of us make the recommendation. I just don't get it.
