I thought replacing this mailbox would be easy... four bolts out and a new mailbox (identical to the old which has exterior issues) in.
But then I noticed the four bolts were actually Phillips head screws there were in there very tight. Using a stubby screwdriver, I was barely able to turn 3 of the 4, but the back left one in the image below stripped on my. I tried loosing these up with WD-40, but it didn't do anything.
It takes most of my arm to reach those back screws and I can't get enough downward pressure to hold the Phillips head screw in while also turning. I also tried a ratchet with a screwdriver bit, but there wasn't much room to ratchet and of course with the screwhead starting to strip the bit wouldn't stay in.
Assuming I get these out, I will try to find similar threaded bots, so a ratchet wrench can be used, but how do I get that back left screw out without harming the wood below the mailbox that it is screwed into?
