The updated Sportwagon sat on the longest available A-Body chassis, 121 inches from '68-69, and 116 inches from '70-72. The 121-inch version allowed for third-row seating so the entire family could enjoy its trademark skylights. While the Sportwagon might not be the prototypical muscle car, there's not much cooler than a fast wagon which is why our A-Body LS Swap systems are a perfect fit.
