The hidden winch mount is not really hidden, it is now an external mount to allow the fitment of a larger selection of winches. This is a new product to me and fitment is also new too as far as vehicle models and years due to variations in bumpers.
Reviving an old thread. I wonder if the OP is still offering this hitch mount, couldn't find it on its website. If it's no longer available it would be nice if the OP could direct us on where it might be obtained.
