Those were for the Art Deco trucks Woody. The real expensive top cowl mounted antenna was the correct GM antenna for the AD's. You may be disappointed in the original reproduction antennas unless they changed them. I had to rework the one that I had to get it moounted. Once again I felt like I had just taken it in the you know what. Really felt ripped after spending $70 plus shipping and had to make a new inner mount and special sleave to get the angle right. There are some snap shots of the problem on this page: http://www.pbase.com/dennygraham/accessories&page=all
