Could you not purchase an easy out drill bit to do this yourself? Like I said, I'm not sure what's holding things together here, but if you can I would suggest drilling on top of the bolt head to fit an easy out bolt/screw extractor bit.. just a thought..
You can usually by them in lets say a set of 3 different sizes for future situations..

I installed a set of hinge mounted lights on a buddy's 5 year old TJ from Chicago (read: rust belt) and to my surprise the bolts all came out without any problems.
A while later, I managed to strip bolt heads, break bolts and break 2-3 torx drivers on my less than 6 month old TJ that had never seen salty roads, go figure.

Post by: superspud on April 16, 2009, 11:43:23 PM: tried the punch, just ended up running a groove around the edge of the bolt. ill pick p a impact wrench tommoro to help witht he few that still have some pattern left.
left handed drill bits are a good idea.

anything i should be worried about when drilling?

Post by: esi on April 16, 2009, 11:55:06 PM: I'm not sure of the name, but I have a impact driver. You put your socket on the driver, put it on the bolt then twist it a bit in the direction that you want the bolt to go then smash it with a BFH. It works great to shock the bolt and get them turning. I'll take a look at the case tommorow and see if there's a name or more info on it.

Make sure your drill bit doesn't wander. Centre punch the bolt, then drill a small pilot hole with a RH helix drill bit, then drill with a larger LH helix drill bit. Wouldn't hurt to use a bit of cutting fluid on the drill and soak the bolt in a rust penetrant to free it up a bit. Oh yeah, be carefull not to break your easy out off in the bolt, you will go through a lot of drill bits trying to drill that sucker out! ;D As much as I hate taking out broken rusty bolts, if you stop by my shop with some kokanee's on Sat I'll help you get them out.
