Ive had the same problem with mine. I tried using one of the bit remover and it broke.
I ended up taking a 1/2 in cobalt drill bit, measuring to the tub and drilling out the bolts heads. Once I was clear of the bracket, they slipped off, then with 2 cans of PB Blaster and a vise grip the remaining bolts came out. LOL.. it sucked.
I have seen the ones you are talking about advertised on TV, I just cant remember the name of them.
http://www.jtsmach.com/jtswebshop/Handtools/HT212.asp These work awesome! I have a set of the snap-on ones and stripped my hood bolts drill a hole pop one of these in " I USED 3/16 " give it a little tap w/ a hammer 1/2 boxed end wrench. It will feel like its going to strip the left hand threads digging into the bolt then a couple grunts and pow out they came. Find yourself the Snap-On Blue-Point Wedge-Pruf Extractors These are even better!

I had this problem when removing the stock hinges off my 99 TJ. Since the hinges were the only real "blemish" on the car (paint was flaking off), I ordered a pair of Kentrol black hinges from 4wd.com. So I broke about 4-5 bits when trying to remove the hinges. Finally I did some research and found out Jeep not only tightens the hell out of the bolts during production of a Jeep, but they also use some sort of glue that makes it nearly impossible to remove the damn bolts.
Anyway, I used a propane torch to heat them up, about 5-7 minutes per bolt, took the jeep down a friends shop, had him mig weld new bolts over the old ones and use the force of the lord to remove the stock bolts. Worked pretty good and they came off fairly easy...and the new hinges look even better.
MAKE SURE YOU DO THIS AT A SHOP, BY EITHER A PRO OR SOMEONE YOU KNOW LIKE A FRIEND THAT OWNS A MIG WELDER.
Get one of those propane torches, with a pencil flame, and heat up the bolts very carefully, so you dont damage the paint on the actual tailgate, and the body. Take about 5 minutes per bolt. Take a T40 bit and place it over the stock bolts, and pound on them a few times with a hammer, that loosens up the glue that you just heated up with the torch. Now try to unscrew the bolt with a T40 bit. If it doesnt go, leave it alone so you dont stripped the bolts any further.
Once you have that done, have them mig weld another bolt (one that will be sacrificed!) over the bolt you just heated up. Then just use torque wrench to unscrew the bolts. You might have to use more than one sacrificial bolt.
hey just read your thead. I had just got a used tailgate my self after hours of cussing the thing i was left with only one torx bolt to remove. You are changing out the hinges if i read right? I ended up taking a grinding wheel and making it into a standard head bolt because i wasent going to use the bolt or the hinge from that tailgate. Just to put another opition out there for you.
