Nah.
Your posts applies as a warning about over torquing the bolts resulting a bad situation.
I have watched a lot of videos of broken bolt repairs. Not trivial.
Seems the ideal approaches is to use a left hand drill that may back the bolt out if it is not seized.
If that doesn't cut it try an easy out but God forbid we break off a hardened easy out in the bolt!
Another approach involves welding a nut on the stuck bolt welding from the inside of nut. Penetrating oil and heat the threads can help.
Else drill out the old hole and use a thread repair kit to bring the hole back to spec.
Torque wrench trivia
Torque wrenches require calibration.
The beam type that has a deflection scale are pretty solid but less accurate. The break-over not so much. Drop them? Don't trust them. Same with torque screw drivers. Some of the cam based break away types can actually over torque a bolt or screw!
Point being the torque wrench being out of calibration could explain why bolts break.
Off topic
The US government has a facility in WV called Rocket Center. It prepares all of the smart munitions for use. Every fastener is tightened using torque wrenches or screw drivers to design spec. They have sooooo many wrenches and screw drivers it warrants them operating their own NIST traceable calibration lab on-site.
The lead technician "Dale Evans" was/is a torque calibration guru. I handed him a collection of torque wrenches, screwdrivers, torque watch gages and he fiddled with each declaring them bad, out of calibration or OK just using is hands. I was impressed!
2 stories from both ends of the torque range ( 2000 ft- lbs to fractional inch- oz)
When testing the high end torque wrench Dale
and an associate put a 6' extender on a 6' torque wrench to test the wrench. I hid in a safe corner of the lab like a frightened kitten.
When testing the low end of the range a small balanced arm supported a small piece of filter paper hold a small measured mass suspended by thread. Dale pointed out how much variability there was in the measurement. I blew in the general direction of the arm and the reading spiked. Dale said he come back on Saturday when there weren't a bunch of fork lfts running around.

Nobody cares much about that here you will find unless it's insanely off-topic.

Speaking of torque wrenches, one thing I never realized is that after use one must adjust it back down to 0 ft-lbs. for storage (click ratchet type). I found this out several years ago when I went to use my torque wrench and it didn't seem to click at the correct torque. That;s when I found out I was storing it incorrectly. I bought a new one. I still have the old one. Can I get it re-calibrated?
You can if you can locate a NIST traceable lab in your area.
We have a Metrology lab at work that calibrated most all the standards we use for our field calibrations. Our equipment is expensive, theirs is extremely pricy
Finally got everything going back together! I bought new flywheel, clutch, pressure plate, throw out bearing, clutch arm, clutch linkage and starter. Transfer case and transmission are rebuilt, now if I can remember how it all goes back together. 🤣🤣🤣
And open headers
The exhaust of course was in the way and the gaskets were already leaking. I’m thinking about using high heat silicone instead of gaskets. I’ve always had trouble with those damn collector gaskets!
I wasn’t going to do this but since the transfer case was out why not rebuild it. In the long run I think it will pay off.
I’m with you on that! I can do it but I don’t care for it. I thought it might be useful sometime in Jakes life. This think is pretty simple compared to new vehicles
I made a list this morning so we wouldn’t forget what we have done on this project. We are getting closer to being done. We have came a long way in 13 months

You are one fine dad HB. Jakes a lucky kid
He’s been a good kid and I think he will take care of it.
Well, he's certainly raised you right.
Jeep, Just empty every pocket!
There are still times I miss my CJ5. Not very often, it was held together with wire and duct tape 
What, no zip-ties?

. Coat hangers and tape
I ordered a new emergency brake mechanism and it was complete made in China junk! So I sent it back and pulled on of the E brakes out of the donor Jeeps. The mechanism I pulled was rusty so I looked around the shop and found enough stuff to put together an E tank. It’s been in the tank a couple of hours and already looking great. I should have done this to start with.
Did you use an electrolyte or just tap water?
Washing soap and water
Borax?
Yes sir

JB Weld and bailing wireI don't think zip ties were invented back then
Have you got a picture? some are actually pretty easy.
