Body mount confusion

[Fuelster]

I have new energy body mounts, so you use your old washers and upper metal cone with these. So my old upper cone pieces are larger in diameter than the energy mounts. Some of mine were rusty so I purchased a used set of mounts on Ebay advertised as taken off of 81 to 87. They arrive and they are also the large rubber mounts. The energy rubbers do fit the large metal parts but are smaller in diameter and there is a space around the rubber and the upper cone. What is wrong here. Anyone know??
