1968 Oldsmobile Assembly Manual – Delmont – Delta – 98 – What we now refer to as ‘Assembly Manuals’ were originally issued by the manufacturer’s engineering department as ‘Product Information Manual.’ These documents served as internal guides for assembly line workers, service departments, and sometimes dealer technical staff. They contained detailed engineering specifications, part numbers, diagrams, and procedural notes directly from the engineering teams, ensuring production accuracy and consistency across all vehicles built. Over time, enthusiasts and restorers have adopted the term ‘Assembly Manual’ to better describe their modern use as step-by-step restoration references.
