Well they have been removed. i decided that while I was rotating my tires i should remove the screws, knowing that more miles would mean more rust and heat making the job harder. I was able to get all of them out with an inpact screw driver except one which stripped. This required a trip to the local auto dealer for a drill bit and an easy out. After a small ammount of drilling they were completely removed. I have to say I feel a weight has been lifted. I have worried about doing my typical Sundy brake job and running into issues. Now everything will go smoothly.
