This is the new, extended-length version of the bracket used to mount the vacuum control solenoid found within our Hush-O-Matic CAN integration kit (06-49195). The extended-length version now comes with the CAN integration kit and is only required to be purchased separately if you are installing a Paco Motorsports ND brake master cylinder brace (14-76140).
Not sure what version you have? This new bracket is 3″ long, and the previous bracket measured 2″ long.
