Downrigger mounts

Has anyone setup downrigger mounts? I’m thinking 1/4 plate bolted to the rails in the back but am curious if there is already a solution.

See Upgrades - rails and drum anchor for rail-setup. I’ve also seen scotty mounts bolted onto the rear locker lids.

Here is what I finally came up with


Used 5/16 rivnuts to mount both these and the pot puller, will be welding wing nuts to the bolts to make tool less removal possible.
