This 4 page listing was directed to the Parts managers at the car dealerships, which was used to identify and order the appropriate exclusive service parts for the Buick GNX.
These items for the G W/GNX-T2L package required dealers to supply the VIN, engine serial number and turbocharger serial number when ordering replacement parts.
All three numbers needed to match the list that was maintained at the GM Service Parts Operations before they were actually shipped to the Buick dealers.
The catalog list supplied the part group number, part number, and basic description of the item within these 4 info sheets.
Most (if not all) of these parts are now unavailable from the dealerships.
[just fyi, any service parts that were common to any other Buick Regal model did not require the special identification, since they were readily available for order]
A copy of these pages would be a neat addition to any Buick Regal GNX owners literature collections.
[occasionally we see copies (not originals) of this for sale on ebay]
