As an old Jeep Wrangler YJ owner I have plenty of experience with stuck Torx bolts. Nearly every bolt on that thing is Torx and they all have the AMC/Mopar rust. One of a few things usually happen- Torx head strips, bit breaks, part of bolt breaks in hole, nothing happens- and sometimes it even comes loose! Soaking the bolt in PB Blaster a few times per day for a week or so sometimes helps. The best method I’ve found is to weld a nut on the head of the Torx bolt. Between the heat and the ability to use a socket and possibly an impact on it will usually do the trick.
