they are pretty easy to do, once you get them out of the car. My motor mounts were already out so it was a breeze. i wasnt going to upgrade but i did anyway and i was glad i did once they were apart i saw how bad they really were. You will need a drill to drill out the old rivets holding the metal shell together around the rubber, and youll have to enlarge 2 of the holes a bit. i had a grinding wheel to help clean off burs and stuff and to speed up gettign rid of the rivets. I took the time to paint them as well and now they look so pretty, lol.
