We first mocked up the upper arms to mount off the rearend's center section, which positioned the arms in the opposite angle seen here. In that arrangement, the frame mounts would have interfered with the rear seat, so we reversed the mounting positions. Either way will work fine as long as the arms have enough angle to keep the rearend from moving side to side. The only problem was that we had to build a new crossmember to mount the upper arms. This would not have been an issue if the car's ride height wasn't so low.
