The 88b motor is only used in softail models and it's counterbalancers are designed to compenstate for the vibration in the rigid mounting.
There is no practical reason that they would put the counterbalanced engine in a rubber mounted application.
Besides the 'b' engine has RPM limitations due to the counterbalancers.
