Just when you thought a plan was coming together doing my brake upgrade Chassisworks sends me the old style obsolete SL6R calipers that now don't match the rear ones. The new style has been out for two years now. I even pointed out to them they have the old style in their catalog and was ensured I would not receive the old style. Found the new style part number that is a match with Wilwoods help. Ugh! Waiting for them to swap them out.....if they will call me back that is. Sorry being patient just a little annoyed
