Multi-mount winch mount for Superwinch Terra 45

I am considering changing from a winch in the nose to the one that fits in the receive hitch so I can fit it on front or rear. I see JD sells one for the Warn and rated for 3000 lbs. JD resells the Warn 4500 but do not seem to offer a receiver hitch type mount.

I cannot find one that fits the Superwinch bolt hole pattern. I see many for the larger winches.

I guess what I really need is someone to weld my current mount to a receiver extension. I wonder if the receiver hitch can handle the load.
