If you're actually going to use it, I'd highly recommend a new hitch. Since they re-inforce the unibody, they get stressed and rust badly in the important areas. My factory 92 was pretty much shot, even before I started seriously wheeling it, to the point that I was no longer comfortable towing our lightweight travel trailer with it. The new one is holding up well, but it doesn't see much road salt anymore.
I got a Hidden Hitch from JC Whitney for the wife's 99 for $120, with a locking hitch pin and tote bag.
