Question:
I have Demco Hydraulic Trailer Brake Actuator - Drum Brakes - Zinc Plated - 2 Ball - 6,000 lbs ITEM 8605001, and the replacement option is Demco Hydraulic Brake Actuator - Drum - Zinc - 2 Ball - 7,000 lbs Part Number: DM72VR However I switched to Electric Brakes and no longer need it and would like to install a Demco Channel Tongue Trailer Coupler - eZ-Latch - Zinc - 2 Ball - Bolt On - 7,000 lbs Part Number: DM15945 However there is no bolt pattern information for a 3 inch tongue 3 bolt. I dont want to assume its same pattern as mentioned above with the 3 3 bolt to 1 7/8 inch to lower bolt that is triangled.

The bolt pattern is the same. I have done several of these going both directions, from the hydraulic and to the non-hydraulic, and the hole pattern was the same.
