my '91 tracker had an aftermarket draw bar with the flat, ball hitch welded to it installed when i got it. not a ball hitch fan, so i got one of the old style jeep 'L' shaped hitch mounts, a 5 ton pintle hitch, and a couple of brackets and made my own.
i'm not a hitch ball fan as i get much more articulation on road and off with the pintle. and no stronger mount on the market. mine has a 2" ball forged into it just in case i need to rent or pull a ball hitch trailer in an emergency. yes, they are a little noisy, but you always know where it is!
pics of it (and my new front bumper) should be on here this weekend.
