GM Service Manual Online
For 1990-2009 cars only

General Motors is aware that some vehicle owners may consider having the pickup box removed and a commercial or recreational body installed. However, we recommend that conversions of this type not be done to pickups. Owners should be aware that, as manufactured, there are differences between a chassis cab and a pickup with the box removed which may affect vehicle safety. For specific information on this pickup, contact GM Customer Assistance. See Customer Assistance Offices .
