at this point, please remove the paper towel, fire up the shop vac over the ports and replace that area with a couple nicely placed pieces of masking tape to block off the holes. form there this issue becomes much easier and cleaner to deal with. can you grab it with vice grips? if not can you grind a tiny slot with a dremel and get it out with a flat head screwdriver? do you need a left handed drill bit to suck it out? let me know where you end up tomorrow and i can send you a new bolt and a tap to chase the threads once the old bolt Is out. patience is key here, we can deal with this, give me a call tomorrow afternoon when your ready.
