My guess is probably gearing, and lack of testing or designing the car to have a hitch and unruly suspensions.
Yes, the transition began then. As it progressed, engineers have been able to produce cars with thinner and thinner sheet metal. The uni-body's today might be "stiffer" than back then, but I have a feeling the old school ones were probably stronger.
