I was told between $125 and $250, depending on how hard it is to get out and if the threads are fucked. We took a micrometer to the outside of the crank this morning, and to the inside of the powerbond pulley. I don't remember the exact difference off the top of my head but there was no way in hell that pulley was going to go on. I'm kinda pissed off now, it was not the bolts fault, I would say the company that sold me the pulley should have said something about it requiring machining to fit, and I'm trying to decide if I should say something about it or not.

Yeah, hopefully that turns out well for you friend.
on the name change thing. That's why I changed my name to what it is today. It has nothing to do with what car I own so I don't go through name changes when I get a new/different car.

You can use a longer bolt, but it MUST be a Grade 8, black, case hardened bolt. It cannot be a Grade 5 or less zinc coated bolt or a piece of all-thread. If you chose to drill it out, make sure to use a center drill to get a start directly in the CENTER of the bolt. Then start with a small drill and work your way up in small increments to the next drill size. The purpose is to drill the bolt thin enough to where you can peel it out WITHOUT damaging the threads in the crank. I cannot stress how important it is to get a start DIRECTLY in the center of the bolt and then drill straight. If the end of the bolt is broke off uneven, grind it flat first. Good luck man, you need it.

I appreciate the help/advice but I already took it somewhere, I'm picking it up tomorrow

I've gotten broken ez outs aroken taps out by bashing them with a centerpunch they are so hard that they just break up and you blow out the bits. But then you still have an off center hole lol

I have had this happen before and I was able to stick my finger in there, press on the broken bolt and back it out. The reason I was able to do this being that without the bolt head there is no pressure on the threads due to the stretching force of the bolt. I damn near **** a twinkie at first at the sight of the broken bolt in the crank and my initial reaction was the same as yours to get the EZ Out going. Just for ***** I stuck my finger in there and voila the damn thing backed right out. The only thing that could prevent this same method from working is a galled/crossthreaded bolt or a tapered crank thread. Moral of the story is don't always jump to the most forceful method before exhausting every other option; I was about 5 minutes from EZ Outing before I tried this...
