O.K., let's start from scratch. The car has an original MII setup on it, right? That system is where the lower arm is a single arm that pivots inside a crossmember and sits 90 degrees to the centerline of the chassis rails. Another single arm runs from the lower arm at the spindle back to the frame rail at about a 45 degree angle to the centerline of the chassis rails. Does that describe your setup? What is the measurement between the control arm bushing bosses on the new bottom arms you bought?
