The "studs" are a great suggestion but they are slightly expensive and once you put never seize on a SS or non rusting bolt you shouldn't have a problem ever again. The true advantage is they make a stud with different size threads just in case you have to oversize the original hole
They are NOT too expensive, compared to the hassle of breaking off a bolt. never seize might work but you still have aluminum and steel there. Studding the bolts puts a steel nut on a steel bolt and that's worth it.
As to removing the easy out, Dremel tool with carbide bit will do it. Take your time with it. Easy out is an oxymoron if there ever was one.
