[Big hammer]

As a16 year old 50years ago I changed the rear motor mounts out by my self before forums. Used a bottle jack with a 2x under the transmission, came out easily, going back in was harder. I did the passenger side first and foght the drivers side. With one new in placed I removed it then did the other side, then back to the first side. I don't remember removing anything else, removing the floor boards and muffler would have helped, I was young and full the vinegar !
