Installed a new winch on my old trailer today

I got parts from a trailer parts place and made a pair of C channel brackets on the bottom of mine that lock into shackles and grade 8 9/16" bolts on the tongue.....so it's removeable and can be stored out of the weather.

I had contemplated the class III winch bracket that can go between the trailer and the truck, but what I made cost about $20 and doesn't add slack.
