Hey Johnathon, thanks for the measurements and the picture. The front two mounting holes on the Demco Hydraulic Brake Actuator item # DM8758721 are 3" on center. However, from the front hole to the center of the rear hole is going to be 12-1/2". This is the closest actuator we have that will fit your old uhaul mounting bracket.
How old is that car hauler?
