In 1968, GM unveiled its compact rear-wheel drive platform known as the X-Body. This chassis is best known as being the basis for the Chevy Nova, but other GM brands got a piece of it as well with the Pontiac Ventura, Oldsmobile Omega, and the Buick Apollo. Thanks to the X-Body's lightness and good balance, this is a superb platform to bolt DSE goodies onto and use as the basis for your street rod, autocross machine, or jack of all trades weekend ripper.
