Most actuators are made to fit a 3 inch wide channel tongue, so if you have something other than that, let me know and I'll look into possible fits. If you have a 3 inch wide channel, then I recommend the Titan Zinc-Plated Brake Actuator - Drum - 2-5/16" Ball - Bolt On - 8,000 lbs # T4079200. Based on the photo, I believe this will be the best fit for your mounting holes.
