Yoke removal help

I'll ask you this, did the bolt break when you put it in, or were you trying to take it out and it was seized up?
The bolt broke while I was driving. I left the house to go for a little Sunday cruise and heard a loud popping as I accelerated and immediately turned around. Before I could get back to the house I heard a loud bang and clatter, pulled over and the driveshaft was on the ground. What happened was the other bolt on the strap backed out and the popping noise I heard was I assume the bolt shearing.

I guess from the responses I should be a little more diligent in my attempts.

Mark the pinion nut before removal as a reference. Use a harmonic balance puller if you want to remove the yoke.
I have already removed the pinion nut so I assume there is a process to putting it back on without a mark?
I think before I spent that kind of money and the headache of rebuilding the center, I would just get the car up high enough to work comfortably on it and extract the broken bolt.

Have you tried to drill a small hole in it and use a small easy out. I would certainly give it a valiant effort, you can't make matters worse by doing so at this point.

I have tried drilling it and using extractor bits but the smallest one I can find is still a little too big and it is hard to get square on the bolt laying on my back under the car. I guess if I maul the threads, is re-tapping it a good option or should I do what furyus2 did and drill it through and put a nut on the back of it?

One thing I was worried about is if there is a crush washer/sleeve that needs to be replaced?

Thank you for any and all responses
