Hey Guys I need some help, I'm working on my 70 GS455. When I got this car it had a fan and fan clutch in the trunk. The fan has a part number 9796134 on it. Above that number there is a series of numbers much smaller they read SD914O07A72. Can anyone tell me what this fits? Is it original to a Buick or some other GM product? And does anyone know how to read the date code? Is it a Jan 7 1972 part? Any help would be appriciated Tony
