How big are they supposed to be, Ted???? I have a part number for a firm bushing that I use for body mounts..... It was originally designed as the rubber bushing that was used on the tri-five chebbie pin type front engine mounts. They have a 1/2" hole, and are about 2 1/2" diameter and are available at Car Quest, Napa, and I would imagine a bunch of other stores. Bushings that are application specific for your Caddy may be a bit hard to come by.......
