pretty much what Dorian said. loosen up all the bolts to the last thread, pick up the drivers side w/ a jack and a block of wood, change mounts, put bolts back in and one thread on the nuts...repeat on pass side. tighten. the rear ones were a pain for both me and HispanicPanic. ended up having to cut them, but you have to do it fron the inside. might have to drop the tank.
