This scanned page contains two exploded-view assembly diagrams with numbered installation instructions, apparently from a factory or Shelby assembly manual. The top diagram covers installation of the quarter panel extension assembly (part 28072&3, callout "AJ") to the quarter panel assembly. Steps direct assembling the extension with three nuts (55734-S2) per side, drilling a .120-diameter hole in the quarter panel using the extension as a guide, driving a #8-15X.50 screw through the extension into the quarter panel, applying sealer X-2922 into the seam and wiping off excess, and cleaning the seam with X-427 solvent. The bottom diagram is an exploded view of the taillight/lamp body assembly, identifying the body assembly-lamps (13434), three bulbs (15198), gasket (13461), lens (13450), door (13449), and screws including 378151-S45. Assembly steps direct installing three bulbs to the body, the gasket to the body, the lens to the body with four screws, and the door to the body with four screws. A reader can learn the correct part numbers, fastener quantities, sealer/solvent products, and assembly sequence for the rear quarter panel extension and taillight components. The document itself carries no printed year, model, or make identification on this page.
