Yup! What he said. Just remember to spin your drill backwards or you'll instantly dull the bit and make it worthless.

 

Good idea to use left hand drill bits. Did not come in my mind.

 

well after soaking the bolts on oil for two days and heating all of them managed to break all 4, and out of anger i ended breaking shock mount beating it off with a hammer. I have looked all over the web and cannot find replacements, and i am going to have a good time drilling out all 4 bolts.
