Hey Richard, I don't have a way to look up what actuator your trailer might have came with so I would need you to get me the brand of the actuator and any other identifying info you can from it. Is the trailer disc or drum brakes? A picture of the actuator emailed to me would also be helpful as well.

The Dexter DX7.5L # DX49FR that you referenced would be a solid option if your trailer has disc brakes and the channel of the trailer is 3 inches wide (this is most common width) but let me know either way.
