This is the jack I was looking for.  If another one becomes available for a reasonable price I would like one for my other 66.;;it has a special pad that just fits in the hole for the body mount bushings.  I don’t know about other years.  It’s suppose to be a safe easy to use jack if your on the road and get a flat.  If anyone sees another for sale I would pay $25.  Came on certain models 78-88 G Bodies, but not all.  Thanks
