Removing broken timing cover bolt

[jdcfamily]

While torquing down the timing cover bolts one of them broke right at the block. There is not enough of it sticking out to get any kind of pliers on it to get it out. Any ideas on how I can remove it?

Also, any ideas on where I can come up with a replacement?

(This is the 2.2 4-cylinder engine)

drill. drill bit and an easy out. or you can drill it out compleatly and use a heili coil.
if its just for the cover and thats it forget about it shouldnt do any harm
