SUCESS!!!!! I got the bolt out in spite of myself.!
The extractor kit did not work. The 17mm was too small and the 18mm was too big. The 18 may have worked except that the shaft on the lug stands only 3/10th of an inch clear of the key slots and it may not have protruded enough for the die to sufficiently bite.
Plan B was to drive an 11/16th 12-point socket onto the bolt. Holding my breath I drove it on and put the breaker bar on and, amazingly, it worked
When the AOS has been installed, I'll figure out what it will take to get the bolts out of the other 3 wheels.
Think I'll have beer to celebrate.
