Yes. When you remove the rear bumper there is a rubber strip between the body and the corners of the bumper. It is held on with 2 phillips head screws. There is another rubber piece above it that sits behind the bumper.
I'm stoked about these too. Didn't know anyone made 'em. Did a quick Google search and this is what I found. $30 aint cheap, but then, where else are you gonna find 'em?
