it looks like you have a rear bearing carrier and not a steering block, I have been looking for a pair of aluminum steering blocks and all I have been able to find are the ones Traxxas makesand they are out of stock in many places that normally carry them I went to addicted2rc's site and all they had was the rear bearing carriers
If it were there, he'd also have a camber link installed. But there's none to be found. The steering block would be mounted higher than the arm, which would prevent it from hitting.
