its a great mount. good rep. but dont know if its worth it on a 92. the 3.0l isnt a high torque engine. its got decent power but its not known for popping mounts. if you drive hard and the engine has a lot of life as well as the trans then it might be worth it.
under normal driving conditions a factory mount is good for 70000 + miles. i even have gotten 170000 ( highway ) out of factory mounts before needing replacing.
Mine is 97k mls, I drive really smooth, but one of them are broken and it is possible to feel the engine "jumping" when I go from D to R. I will try the mount, it is not a daily car, just a car I will keep because it is in really good shape and dont worth selling it.
