I bought a centerlink for my 66 SS396 project. The catalog listed 64-67 chevelle. The centerlink is the right length, but it hits the frame, and I cant turn the steering. The offset for oil pan clearance is about 1/4" more than the original centerlink, this is why it hits the frame. Could this be for a 64, and not the same as 66? I thought 66 & 67's were the same, but different than 64 & 65's. Where can I get the correct centerlink?
