If you buy the motor mount from Mike I believe it comes w/it. I have a mbx-5 I converted to brushless and my motor mount came w/ a steering srvo mount made out of Al. I chose to cut my carbon fiber mount to save weight. Either way it will work. I am considering putting the Al back in...
I found the link for you...
