Never installed, looks to be a replacement. AC Delco, I took it out of the package to make sure it was perfect, and it is. Fits my 69 base perfectly. Hard to take a picture of an antenna. Has the stainless ball on top. Pay Pal and I'll pick up the fees. $60 shipped to the lower 48. If outside the US, just let me know and we'll see what it will cost. Thanks, Rich
