I used everything I could from the donor car (1998 Pontiac Grand Prix GTP). The Pontiac front subframe mounting points were modified but the rear is stock. I fabricated the front frame supports using 3x5 tubing and in the rear 2x3. Eliminated the Mcpherson struts by making an upper control arm bolted to the Corvair subframe. I used Aldan American coil over shocks attached to a welded mount on the bottom Pontiac lower A arm and attached the upper shock to the stock Corvair location. The Pontiac being a FWD setup, I used its rear adjustable torsion bars, cut them to size and attached them to the steering knuckles to eliminate the steering. The front suspension is a rack and pinion unit with Corvair modified steering arms to achieve proper Ackerman geometry, disc brakes and the Pontiac steering wheel.
