Replace motor mounts (1 answer)

My car is actually a 1989 but wasn't given the option to select that. I need to replace front and rear motor mounts. Is it possible to do this myself without going crazy or tearing up the car? Have been looking online for instructions of any kind but haven't been able to find anything.
