I, too, prefer the look of "period correct" wheels. Here is a pic of my `77 with 14 inch Panasports.
And as an aside, if you (like me) view your Spider as a long-term item ('til death do us part') money spent on quality wheels with timeless styling is well spent. I've had these Panies on for twenty years now. Thet still look fresh and new. More highly styled ones perhaps would not and less well constructed ones may not have lasted. (Panasports are favored by rally drivers because of their durability).
