I have a front tower strut brace from a u13 attessa and you are correct greenbird. It does fit on the aussie bluey, but the AAC valve is in the way. I had it on my car for a few weeks, but then removed it because the pipe would hit the strut brace under throttle. It also caused my car to stall everytime i put the clutch in to come to a stop. As soon as i removed the strut brace i had no problems with the car stalling.
