I think that a torque-arm would be the best bang for your buck as a company. Fairly simple in parts but heavy on engineering. Having the 8 3/4 allows for bolt on mounts for the arm and use of the front sping hangers for the other two links. Use a watts link to square it up. I would do a combo of the Cortex and http://www.totalcontrolproducts.com/rpss_fd.html
without the pushrod component for the shocks. If I had the engineering I would build my own. Similar wheel bases on the cars so probably would be close. I tried to work with Filip at Coretex but he became too busy on mustangs.
