Engineering:GM H platform

From HandWiki

The H Platform, or H-body, name has been used twice by General Motors. The 1970s H-body was an inexpensive rear-wheel drive compact automobile platform from the 1970s, used for the Chevrolet Vega and Monza and their Buick, Oldsmobile, and Pontiac derivatives. The 1980s H-body was a front-wheel drive full-size car platform, and was the basis for GM's second generation downsized full-size cars, which included the Buick LeSabre, Oldsmobile 88, and Pontiac Bonneville.
