I have changed a wide kingpin beam to a 6" wider king pin beam. The beam uses 4 spring packs with 4 adjusters. I bought the beam off a running car that way. After having to do some work on the beam and bushings, I have removed the stock arms and have installed bigger arms. After reinstalling the beam, I cannot get the front to "flex" (for the lack of a better description). Can't get the arm stops re installed either. Can anyone here help?? This baja is strictly for my fun and not for racing.
