I have a set of rare correct numbered 66 mag style hubcaps. They are nos however I don't have the GM boxes they came in . I have saved them with intentions of using them on my 67 SS but they truly should go to a 66 L-79 build. They will look similar to a 65 Z-16 Chevelle cap but are a specific number to the Nova. Also I believe there is a slight difference in color . They are not cheap but are the right caps for the right guy doing a high end build. $2,500 set of 4.
