It's a metric and has an 18mm head as I recall. Might be a 19mm but I am almost certain it's 18mm... which would put it at an M12, not sure what thread pitch. I seem to recall it being about 30mm long.

Since you are only missing one, why not pull the other out and bring it to your local Grainger or Fastenal? They have thread gauges and can probably sell you a new one.

If I understand that you are talking about the rear portion of the transmission to crossmember mounting then 5201 7887 BOLT, Hex Flange Head, M12x1.75x25 is what I could find listed in the 1997-1999 parts listing. They had it listed under the heading of engine mounting rear. Kastein nailed it almost perfectly! Hope this helps. If I have the wrong bolt let me know and I'll recheck for you.

FYI - Made in USA M12 bolts have M19 heads. Made in Canada M12 bolts have M18 heads.

In my parts book it is listed as an M12x1.75x25.

That is in the 87-90 parts book, guessing that your user name has something to do with your XJ's year.
