The deluxe wheel with the bird in the center was standard on hardtops and ragtops, and came with the decor packages which were optional on the coupes, basically it was giving you the hardtop interior and chrome exhaust tips for your coupe. I don't know how rare it is I think they made 33000 or so coupes maybe just over half?? had the decor package so I would guess 10,000-ish came with the belvedere wheel but who knows???. I think both set ups are neat but I always find it refreshing to find a non decor packaged coupe kept in it's corrrect state. slightly off the subject, In the reference section in "dealership referrence " there is the "color and trim selector" that shows the difference in seats and door panels from standard coupe to hardtop.
