ordered mine from import palace. It is just the upper mount, no need for any others I would post pics but dont have a way to take the pics and get them on here. i think there is a pic on import palace website.
Just like the MM claimed, I think it cured about 90%+ of the wheel hop. Vibration at idle is less with this MM than my ES inserts. However, there is a whine from the power steering unit, which was not there before. I would still recommend this MM to anyone. It's a nice piece.
EDIT: I removed my bottom ES insert. It was suggested you run just the JLM MM by itself.
