    Hello I have a problem with a fan clutch from a 71 chevelle, I recently tried to replace it and the bolt pattern to the fan is different. It is very wide as the middle hole is 3 1/2 inches round. The fan clutch has a brand logo S . It has a number 032571SC stamped on the part where the four screws go to connect to water pump. Does any body know what this is? The fan has 3989095 stamped on it. The ones shown in the internet look exactly like mine but the bolt pattern is different it is smaller and the four screw pattern is smaller.

    Also people change things out thru the years.. Might be from a different year car/truck
