1978 GMC Chevrolet Medium and Heavy Duty Regular Production Options (RPO) Parts Book. Original.

Regular Production Option (RPO) Service Parts Lists are used to service Medium and Heavy Duty Model vehicles built with factory installed options. These lists contain only those parts that were needed to make the RPO installation and that differed from the standard parts normally used. Refer to the applicable Medium or Heavy Duty Models Master Parts Book (NOT Included) for all standard parts related to but not affected by the RPO installation.

Condition: Missing Cover. Parts Books are used in Dealership Shops, Independent Garages and in Fleet Environments and thus can reflect such use, most often showing extensive signs of soiling, age, and wear. The information within is still legible and can give valuable insight. The images shown are representative of what is shipped. An informative piece that will be a great and useful addition to the GM Truck Owner or Collector.
