if by "cone shaped" you mean this style - no, that was 57-60 only .... there's a few 61's in the gallery with original caps, like this one, and I believe they actually don't use the clips, it just took GM a couple years to stop adding them to the wheels, and quite a few more years to stop adding the holes for the clips
