as the man said easyouts are great until the damn thing snaps off in the hole.. before using the easyout you could try heating the nipple..then quenching it with cold water.. and again and again.. the expansion and contraction can break the bond.
another way is to use progressivley larger drill bits.. make sure that you dont go bigger than the thread tapping size..often the heat generated by drilling will break the bond..when drilling with the last and largest drill bit, reverse the drill.. go gently and it may twist the remains of the nipple out without damaging the thread. or a combination of drilling and easyout/torx bit. go easy with the heat..remember there are rubber seals in there.
you have nothing to lose really as if you bugger it up it's off to the machine shop.
oh yea and I wouldnt use an easyout from e bay either, only use the best quality..
pity about the paint job..I'll leave mine nice and rusty..
