I'm putting a 4 link into a 59 Mercedes 190sl, along with a 5.0 L A.O.D., 4 wheel disks and a bunch of other stuff. Basically it will be an A.C. Cobra with a different body. On the rear suspension, it will work alot better for me if the upper control arms are mounted wider apart on the rearend than on the frame. I've only seen them the other way. Theres a little box behing the seat that acts as a compartment for the stereo, etc. I'd like to save this. If I mount the upper bars the normal way they would sit in the middle of this box. The horizontal angle is not a problem if I mount the bars closer together on the frame. Any thoughts?
