Should fit, I believe the frames are the same. It looks like the stand my Jackal came with.
I'll echo the "should" fit.
IIRC (and this was a while ago but I'm probably close on the details), when I first bought my Jackal in ~2003, the dealer also sold me an accessory used centerstand from "another Tonti model". It did indeed fit, though it might have been a little short as it couldn't fully lift the tires off the ground when deployed and IIRC it was narrow too and the feet were uncomfortably close to the rear tire enough for me to grind away a little assurance on each of them.
That said, I'm pretty sure it was off an older Tonti and a 98 and 00 would have been much more closely related so you're probably fine.
