Drivetrain Seized drive shaft bolts

I did this about 6 months ago.
Use heat from a torch & they will come out easy with an impact wrench.
No ones uses a torque wrench to put them back. They use an impact wrench instead.

If you have ruined the bolt heads, you are screwed. You will not be able to drill them out.

I was able to drill one of them out, it was a nightmare as you said, I've cut the heads off the rest and was able to remove the rest of the bolts. I wasn't able to find a 12mm 12 point impact socket and had to try with a regular 12 point(which stripped immediately), even after torch-heating and cooling with a penetrant, impact, pry-bar you name it--they wouldn't budge.

In any case they're off now at the cost of the u-joint adapter (flange?) which I'll have to replace as it took some damage from the grinder.

I'm sure better technique would have helped me out on this one, but I'll cut my losses and move on. I'm just learning as I go here

They don't make 12 point impact sockets which is why you can't find them.
Torque new bolts to 70-95 lb-ft. with blue Loctite.
