You guys are right. My fan blades join the fan arms off center with 3/4 of the bent blade hanging over the arm and 1/4 of the blade is where the actual rivets are. It resembles a kitchen knife with the blade hanging be low the handle and the other side of the blade is level with the back of the handle. The GM arms join the blade almost in the middle with the blades actually hang over the arm on each side.
Sorry to be so technical
Is the Camaro and Chevelle fan for the L78 a different design then the Nova's ? Those cars don't sound the same as a Nova.
The GM fan is pricey.Does anyone know of a truck or other GM model which is similar.
