Ok, here is the Cossie electrohydraulic servo connected to a mk4 RST firewall using a 2cm thick spacer to change the bol pattern. Luckily the pushrod is 2cm longer on the Cossie servo. As you can see, not much of the package comes below the master cylinder line. The lowest part is the ABS actuators that can also be removed to my knowledge if/when ABS is not needed.
