2005 TJ windshield frame and bolts seized, broken, extractor snapped off..HELP

[JOBO]

Long story short:
2005 TJ with broken windshield & rusted windshield frame both need replacing.
Half of the torx bolts on both sides were seized...and then stripped...
I've tried:

• PB Blaster to loosen them,
• a torch,
• dremmeling a slot ,
• drilling them out and
• inserting an extractor.

This worked on only two of the bolts.
Three..of them have broken drill bits or broken extractor tips inside them.
What do you do when penetrating spray, torch, dremmeling, drilling, and extracting don't work?
I'm literally thinking about hacksawing the window hinges and having the new window frame welded on.
Any thoughts?

Try Liquid Wrench, wet the bolt, then lightly tap tap tap with a small ball peen hammer. The tap tap tap helps the Liquid Wrench get into the threads. Repeat every few hours for 24 hours. Then try the removal things you already tried again.

When you are that far in... Im not sure. When drilling out use cobalt drill bits and lubricate. The bits are hard but shatter if you push too hard or bend the bit. If you break a bit diamond is the next hardest.

The bolts have loctite from the factory. Using a sharp torx bit and cleaning out the bolt of paint or debris. Make sure it the torx is a tight fit. PB blaster soak. Put the torx bit in and heat with a torch to soften the loctite. Tap it a few times. Start to loosen. Do not use a breaker bar as you are likely to strip the bolt quickly. When you get the bolt to move a bit rock between tightening and loosening. Reheat between. The rocking breaks up the rust and allows the penetrating oil to work.

^^ditto on the tapping the back of the torx bit after heating.

This is sharp. Note no rounded edges.

Also, sounds crazy, but has worked. Tighten it, then loosen it repeat.
