Hey John,
Since we're clearing things up around here, when did you move the acceptable year marker to 1988...the HOME page still says Pre-1973
In the late 1960's early 70's Chevrolet made the G-Series Sportvan (windowed passenger van), Chevy-Van (cargo van) and small FWD Control vans (which look like the mid-60's vans with the engine along side the drivers seat). The larger Step Van's (bread trucks) were built on the P-Series platform with steel or aluminum bodies or sold as a Chassis only for use as a motor home or custom bus.
