I removed this 7 blade from my 1970 NOM 350 Corvette. This was a working unit when I removed it. On the back of each blade is the following: 3931002 913894 K 67. I have no idea which GM models this fan & clutch would fit. Nova, Chevelle, Camaro, Caprice? I don't know, but I do know it'll work on a 1970 Corvette. It measures approximately 17.5 inches across.
The front of the blades had been paint black by a previous owner, but as you can see the paint started to come off when I sprayed degreaser on the unit. I have more pictures if needed. $100 OBO + shipping
