Any Ideas on how to take it off?, I've tried with all sorts of sockets and wrenches, and even vice grips and no luck.. any help would really be appreciated, thanks.

sears has a tool there like vice grips only there for stripped bolts iv used them for that same thing.

There is a tool that they sell just for this. I have a set that I got from sears.
I haven't got to use yet(luckly), but I keep them on hand just in case. The just go on like a socket, but has teeth to grab the stripped bolt and remove.

PM80 has the right idea; they're sort of an inverted easy-out, with hardened, sharpened flutes inside the "socket" to grip the stripped bolt or stud. If those won't work, you can always get a set of easy-outs; everybody should have a set of those in the garage.

make sure you have a new back up bolt ready!

and those sears kits work wonders

Worse case scenario...if you have room, you can take a slightly smaller socket and pound it on about half way...then tack it with a welder. Should spin it right off. I had to do that once on the race car about two in the morning when no one was open to buy what I needed and I was nervous to drill and use an easy out. Sometimes that doesn't work out and you're left with a mess.

Reverse rotation bits usually work great. Sears has a set that has extractors built into them. The work great. Gotta love Sears.

I've used those! They work fantastic if the bolt isn't seized or cross threaded. Of course, when that happens, you're screwed no matter what you do.
