Item is the 1978 Cadillac Preliminary Service Information Manual.  Produced by the Service Department of the Cadillac Motor Car Division, General Motors Corporation, this manual contains preliminary service information for the 1978 models, prepared before all of the final production specifications were established.  Complete service information is contained in a final service manual that was released in December, 1977.   The 1978 Final Shop Manual will supersede this manual. Refer to the 1977 Cadillac Shop Manual for service procedures common to 1977 and 1978 models. This is NOT a reproduction, reprint or copy - but a used factory issued manual.  As a result, it does have surface wear and some grime in and around some of the pages, but is otherwise in good condition.
