Factory Assembly Manual, 1972 GTO/LeMans/Tempest

The most valuable reference source there is

No other book gives you the kind of detail that this does!

The "factory" manual is what many consider to be the most valuable reference source there is available. From cover-to-cover, detailed, blown-up diagrams illustrate each and every component in the particular year model. Includes breakdowns of all parts and how they fit together with an accompanying GM part number for each item. These are the original factory diagrams that assemblers used to do the installations on Pontiac A-Body vehicles.
