Thanks for the info. Also, thanks JFB for the chassis drawing.
We did measure the track hub center to hub center at both sides. They were about the same. The rear lower control arm adjustment shims are removed. The rear upper arms are stock. The front upper control arms are custom adjustable units. The front lower control arms have been lengthened to minimize excessive scrub radius. The longer arms have been compared to straight stock arms. After aligning the car we then realized the wheel base dimension was longer than stock. I’m comfortable redesigning and making the suspension work but I would rather not reinvent the wheel and keep things as close to stock. We are trying to confirm that the chassis wasn’t modified. We are currently setting the steel flares so we want to confirm the wheels are in there correct location. The drawing JFB posted has a dimension in red of the distance between the front mounting hole for the lower rear control arm to the lower front control arm rear mounting tab. That’s what we need to determine the chassis has not been modified.
