Just a suggestion - in this case, when the OEM bolts were put in with the yellow Locktite, or factory product, whatever it is, they are very difficult to remove. Getting them out without using some heat, may put some extreme stress on them, and could cause them to fail later. You really don't know if the factory torqued them with an accurate torque wrench either. It is possible the factory has a bolt runner air gun set at the required torque and is running them in with that or something similar. The settings and adjustment on the air flow to an impact gun or even an electric screw runner are not nearly as accurate as a hand operated torque wrench which has been tested and you know it is very close to what it should be. The hand operated torque wrench, in the case in your tool box, is also not on the assembly line running in bolts eight or more hours a day. Your torque wrench will probably be much more accurate than whatever the assembly line is using.
If you are really concerned about the bolts that the manual says are for one time only usage, then you could put new bolts in the first time you have to take them out, and then put the new bolts in with blue paste Locktite, so that they are not exposed to extreme stress getting them out the next time. You will be putting them back in with your own pampered and tested hand operated torque wrench, so they should never be stressed as the OEM bolts probably were. Of course, the factory reps nor the dealerships are going to tell you the what the assembly line does torque the OEM bolts, so it would be a waste of time asking for that information. It would be a lot of trouble getting the broken Locktite covered stub of a bolt out so you could replace the bolt, so it might be worth changing out the bolts at least one time. The cost of a replacement bolt would not be near as much as the expense of your time and trouble getting a broken bolt stub out, much less several of them. It is just a compromise you could consider.
If you ever get a chance to tour an assembly line of anything, look for the guy who comes along, after the other guy with the screw runner gun gets the bolts lightly seated, and then torque wrench guy torques them down to specs. You won't see the torque wrench guy on any of the uTube assembly line videos either. Many of them are robots arms and some human mechanic might come along after all day running to test and set the torque pressures, but you won't see that in the video either, nor on the assembly line tour.
