So taking a sawzall to them to remove them is out of the question? J/k. But I am removing them as soon as I get home from work today. I don't want someone stepping on the broken one and hurting themselves.
ETA: 45 minutes later...I've realized that a 10.4 volt drill with ton of bits, isnt a replacement for an actual socket set. I need to buy tools, rusted in bolts aren't coming out at 10.4v! The brackets (that metal bar) literally fell apart in my hands...but the screws that held them in..nothing
