If u busted a bolt, likely tight enough to bust an undrillable easy-out.
My preferred easy-out is straight spline type, NOT the tapered ones with spiral flutes. Would be very cautious .... mabe preheat area with propane to about 300-400 F (reg oil or 100% antifreeze boiling point). This allows alum to grow away from metal bolt.
Better to patiently just drill out, use dremel or file/punch to get a good center for 1/8" starter drill. Max drill size is 1/32 less than size that drops in the other tapped hole. Use dentil pics and correct tap to restore original thread. Careful use of dremmel with 1/8" carbide burr will help.
