Yeah found that bolt. Removed it. The funny thing is my car has no rust. All the bolts came off fine. But the darn ABS sensor is still stuck. Even got a pair of pliers on it to try and wiggle it out. One more question

It seems the ABS sensor is "plugged" into a small light colored "mount" that you can see easily in the second picture which is bolted to the dust guard. Does this entire mount come off of the dust guard, or does the abs sensor pop out of the mount? It would make sense the bolt would free the ABS sensor/mount combination, but it seems like it is welded to the dust shield.....Or is this just rust?
