Removing frozen foot pedal bolts for MCOR access

[Midiman]

I need to replace the MCOR on my 2018 Precedent. The left two bolts are very rusted as we are near the ocean. One immediately stripped out the torx when I tried to remove it. I’m presently bathing them in break away, but I was hoping someone might have suggestions. I know they are extremely long so if I cut the heads I can’t imagine drilling them out, and if I do cut the heads I don’t know if there will be any stubs left to get a pair of vise grips on. Unfortunately I don’t own a torch… not sure if my butane cigar torch might help? Thanks…

Are these the bolts that hold the pedal mount plate to the floor?

Cut a notch in the head with a cutting wheel and see if they might loosen with a large flat-head screwdriver, or just cut the heads off.
There should be enough stub sticking up to get vice grips on. I'm pretty sure those just go into plastic, so a torch is not a good idea, but it does mean if you can get them to pop loose then replacing them will be easy.

It is those bolts. The right side were easy, the left side were totally rusted. Thanks I’ll give that a try. I watched Wayne Martin’s YouTube video How To Install An MCOR and the bolts are extremely long. I have a feeling that in the end I will have to cut the heads off. It’s just that it is recessed opening that the plate sits in, so I don’t know if I will have much room to get vise grips on unless it leaves a good size stub. I can’t really see what it looks like with the pedals removed in the video.

Neither Dewalt (which I have) nor Milwaukee is gonna help here. The screws are Torx head, so they must act like little pools for moisture to gather in. They both immediately stripped out. I cut slots and tried using a big screwdriver but they were pretty much welded in with rust. I ended up cutting off the heads to remove the pedal pan. Then I drilled out the screws the best I could, and proceeded to break off a tap trying to tap them for screws. Then I proceeded to drive the cart over my head to put myself out of my misery.
I did manage to tap one of the holes, so three screws will have to do.
