Hydraulic Actuators in Series

Hello,
I am trying to model two hydraulic actuators in series such that if actuator A expands by 2 inches, actuator B retracts by 2 inches.
The pic attached is what I have so far. Port A is from a hydraulic suspension and has varying pressures, but are all in the range of 1,000-10,000 psi. I think my issue is that since the C ports on both actuators are attached to ground and both R connections are connected, simulink thinks both actuators are in parallel and fighting together, rather than in series and fighting against each other.
Does anyone know a way to adjust this so the 2 actuators are fighting against each other?

There is a setting in the converter block about whether pressure in the volume causes the R port to move in positive or negative direction. There are a few example of a double-acting cylinder assembled this way in the shipping examples. Like this one:
Mimic its setup and you should be OK.
