Does anyone know what part I'm referring to? My passenger side motor mount is in pretty bad shape, but i noticed a "Saucer Like" looking bushing that comes off the bottom of the square stock rubber mount. The thing is maybe 1" to 1.5" in diameter and all i can describe it as would be a spherical to "saucerish" looking rubber bushing or mount of some kind that is either below the mount or between it and the block. The mysterious bushing or mount has basically disintegrated and has a bolt that runs directly through the center of it...I'm not sure if this bolts to mount itself or the K-member. the only thing i do know is that there is the exact same thing on the driver side but it's attached and very hard to see; as it covered by road grime and many metal lines maybe power steering lines or brake lines... i don't know. When i replace the motor mounts, is it best to use the stock replacement or something after market...my car is basically stock Any help would be greatly appreciated.
