The strut mount is integral with the bearing plate. One thing you'll notice when youcdo this repair, is just how warped the bearing plate becomes after time. Which is why adding a strut tower brace to old strut mounts is so difficult. The upper spring mount which sits in the center of the bearing plate, would be a good idea. When this fails, it often causes clunking, and it isn't an expensive part.

I am assuming you will get all the hardware that goes along with the strut plate, such as bolts between the strut and steering knuckle, and nuts for the bolts on the strut mount. Besides that, I can't think of anything. But with so much removed from the car, it's a good time to do other things like springs, and control arms.
