1960s

- The steel unibody was widely used among European auto manufacturers.

- The latter end of the decade was marked by the development of the steel unibody’s premier internal standards and procedures.

– A body with structural functionality, using the Ruler Frameless model, was H.J. Hayes’ answer to reduce the costs of car production, as well as the noise and vibration during the ride. So what was this Ruler Frameless stuff? It was a car manufactured in only 3,000 units, which had tubular-shaped body panels for solidity, plus an engine and suspensions attached to a horizontal floor-pan.

– A bright idea came to Edward G. Budd, “Eureka, a car of steel!” However, this didn’t materialize because of these factors: (1) the stamping technology during that period still wasn’t good enough to produce sheets with complicated curves (2) the need for too many parts and welds to link steel sheet shells together.

– But though Budd didn’t see his own steel car come to life, it inspired the steel unibody, which was adopted to create the Dodge Brothers. It was a steel car all throughout that became the first to be manufactured in thousands of units.
