Correct Replacement for Demco DA66B Hydraulic Trailer Brake Actuator

Question

Question:

I’m and oooking at the item Demco Brake Actuator - DM8608601 for my trailer. My trailer already has a demco hydraulic tounge. Is there a way to know if this is a direct bolt on replacement for my trailer. It’s a basic steel deck double axle car trailer. The current demco tounge on the trailer says 6000lbs da66b is all I can make out on it.

The Demco Hydraulic Trailer Brake Actuator part # DM72VR will be a direct replacement for a DA66B. It will mount using the same holes so install will be a breeze. The bottom hole can be left untouched.
