I probably could have put this in anytime, but years ago I asked Al if I could just buy the upper portion of the Spirit coil-over kit and continue to use the Eagle's lower section and he responded that it would work fine. I was just wondering if Control Freak decided to make a tube style lower control arm for the Eagle. Good thing is though, the lower control arm is boxed in which is the next best thing to tube designs. In time, unless a dedicated kit comes out, I will probably buy the upper portion of this kit (if Al will still price it that way) and use the factory lower control arms.
