you need to go to auto parts plqse and purchase some liquid wrench and spray down all rusty bolts that you need to replace.let it sit for a while so it can penetrate. take your old broken bolt with you and purchase a drill tap that you can drill out the bolts .this is the same process you use when brake off head bolt.

ok witch bolt is it. On most tuff bolts that I break trying to remove or install I use a left hand drill bit and then if that does not catch and remove I use an easy out but let it soak for a while with some WD-40 first

You can try to drill out the broken bolts, or you can use heat, if you can grasp the bit of bolt poking out the back side of the plate. Get the bolt tips red hot with a torch or as hot as you can. Grab the parts of the bolt with a vise grip pliers and try and turn it out. If this does not work, you will have to drill a small starter hole in the bolt to weaken them and allow it to shrink a-bit and turn out.

oh boy? this is a good un, you can try to drill out the broken bolt but dont drill the threds out,, or drill a smaller hole than the bolt and use an "easy out" to undo the broken bolt,,,if you had used a bit of wd40 or a bit of heat on a sezed bolt first it may not have broken off,,,,this could now become expencive

You will have to drill a hole in the middle of the bolt and use a large ease out. Put it in a drill and move slowly.

There should be rivets holding the window to the regulator. You have to drill them out and replace them with nuts and bolts.

have you tried useing an EZ out exstractor or left handed drill bits that can be picked up at any automotive store or tool store. If that does not work try completey drilling out the old bolt and rethread the hole for the bolt. If its on the strut and the bolt will be replaced with the new strut try useing a cut off tool to remove the bolt just to remove the strut and replace.
