I have a Bilstein setup that uses the ISC mounts. They are a modified stock housing that is basically threaded at the top for an AWR cap. Don't know if the length of the tube is the same as the actual AWR mount but it's obviously very similar.

I love the Bilsteins! Huge improvement over the Konis we had on the car before. They are much more consistent through out a race. No problems with them so far either.
