If this is the same center link as a 63 B body, the link fits on two ways. There is about .75 inches in clearance between the two. It looks like it won't make a difference, but it does. And it would seem the "right way" the link looks, is actually the wrong way.

As I recall, the link, shaped like a "U", the bottom of the "U" goes to the front.

I checked a bunch of cars at the track last summer, and everyone, including my race car, was on backwards. Handling and geometry are the same either way, but it makes a clearance difference.
