This 1967 Pontiac Firebird convertible looks close enough to factory-stock to fool a casual glance — until you learn the restoration shop deliberately built in modern parts to make it run and handle better than it ever did new. Shop owners Chuck and Debbie Woolery walk through exactly what changed and what stayed original on this Pearl White, 400-cubic-inch first-year Firebird, shown at Chicago’s World of Wheels. Watch to see where the line between restoration and improvement actually falls.
