We do not have a master cylinder repair kit for your older Atwood surge coupler but we can help you select a new coupler to match your trailer gross weight. The linked page displays both disc and drum brake surge couplers; just click on the type you need for your trailer, the ball size and then click on the gross trailer weight rating (GTW) that is appropriate.

A popular option for a 7K GTW with a straight tongue and drum brakes is Demco drum actuator coupler # DM72VR which is a bolt-on install. We also have A-frame couplers like 7.5K # T4067600 which takes a 2-5/16-inch ball.

You can certainly go ahead and re use the existing 2 bolts, provided they are in good condition. The fish wire method shown in the video works too, but it is also very common to just use the two bolts like your old Atwood actuator. Personally I would…
