What about one of these mounts.
We have this one for sale, yes its used and yes it works good.
If the bolt holes are the same as a TJ, then I have one that I will give you Rich.
Hiding the winch is great, provided it NEVER gets used. I always want to visually inspect the winch, and the wire rope. Expecially to make sure the wire rope is correctly wound, not bound, or kinked.
