1970 Pontiac Firebird A/C Hose Clamp & GM Drawing 3965175 - C60 Air Conditioning

This image shows a physical restored/painted black metal clamp or hose-retaining bracket (with a slotted mounting hole and a circular loop end) laid on top of a photocopy of a General Motors factory engineering drawing for an air conditioning installation. The visible portion of the drawing illustrates the air conditioning compressor assembly (labeled 'COMPRESSOR ASM') and the 'AIR CONDITIONING HOSE' routing at the front of the engine compartment, including a hose passing through a grommet or bracket. The drawing's title block identifies drawing number 3965175, UPC code C60 (the GM option code for air conditioning), and sheet D5. A revision record column lists entries including '"DEHYDRATOR"', 'DWG REV'D', and authorization numbers 27236 and 28744. The part placed on the drawing appears to be the actual hose or line clamp depicted in the diagram, apparently photographed to document its identification against the factory drawing. A reader can learn the GM drawing number (3965175) associated with this A/C hose clamp/bracket and see how the compressor and A/C hose are arranged per the factory C60 air conditioning installation drawing.
