The Demco Hydraulic Brake Actuator part # DM8104311 is a fit for trailer tongues 3" wide. If this is what you have then it will work well. If you are however looking for the bolt hole spacing then you can reference the attached photo.

How much frame length does the DM8104311 use? I need to know if I will still have room for the trailer jack.
