Is yours welded on or bolted on the bolted one can be turned upside down and a retaining pin chained on it, the bolt idea works or you could weld two recovery eyes to to your new winch mount, I see your using the original implement mount bolt holes I’d be be tempted to run two plates down the sides. I’ve seen winch mounts pull of the front of Unimogs in the past on my own machine 😂
