Several years ago at the Nats I struck up a conversation with a gentleman who was displaying a nice ‘78-‘80 Regal. Turns out he was Ron Frakes, a retired chassis engineer. His telling of all the detail work, testing and retesting shocks, sway bars and braces was fascinating. Even when the cars were moving to more common parts and shared components, Buick was still trying to set itself apart where they could. Whether it was big stuff like pushing the turbo program (and the parts that went with it like the 8.5 rear and better built 200-4R) for ten years or little stuff like squeaks and rattles, it made a difference.
