cannot undo TPS bolts

[undecided]

went to replace the TPS on my 98 4.0litre cherokee and have not been able to undo the 2 x T20 bolts that retain it.
I first tried on the vehicle just to undo them and broke the first torx bit. I then removed the throttle body and tried the following.............
IMPACT hit the head of the bolt to try and jar it loose.
PIN PUNCH used on the side of the bolts with a hammer to try and turn the bolt
VICE put the bolt head in the vice and turned the whole throttle body
what I have not tried
Drilling the bolts
Heat, I am loathe to put heat near plastice sensors.
So any other ideas?
has anyone else had a similair experience ?
Does anyone have a throttle body they want to sell ?

put into a hydraulic vice on a milling machine and use a carbide drill drill it to the thread minor diameter and then pull the thread out with a pair of pliers
lol
but i doubt u would be able to get a hold of any of that

I broke the original TPS into pieces so it could be removed, than used vice grips on the exposed screws
