This is a scanned page (numbered 239) from a General Motors Corporation assembly instruction manual, photographed while still in a ring binder. The page shows an exploded parts/assembly drawing with numbered callout boxes (1, 3, 5, 6, 7) pointing to small hardware such as screws, push-in fasteners, and two bracket assemblies being installed onto a panel or floor/firewall area. Several locating dimensions are given on the drawing (1.47, 1.83, 2.40), along with reference callouts reading "30 P.K." and what appears to be "44.6 P.V." The drawing notes ".424 DIA HOLES" and "DIMPLES" as locating features for the fasteners, and the view is labeled as applying to "3-4 SPD STD TRANS" (3- and 4-speed standard/manual transmission applications). No legend, part numbers, or fastener specifications are legible in this photo, and the page title is cut off beyond "INSTRUCTI..." A reader can learn approximate bracket mounting locations and hole dimensions for manual-transmission-related brackets, but companion pages (likely elsewhere in the same album) would be needed for the parts legend and full context.
