I did the dremel tool and no luck
I did get the passenger side off and changed....the driver I did the following:
So I ground the screw head off to level with aluminum channel and then replaced the fuzzy as the track stayed in the car. The screws were so rusted in place I know the channel isn't going to fall off.
So I changed the fuzzies, but did not get in new screws. Worked just fine for me.
