12 bolt issues. Need advice

[Sean1985]

I was in the process of cchanging out my rear axles and disc brakes but didn't get too far. I was taking the bolt out of the rear end that hold in the spider gear shaft and the bolt was broken. I still have a little threads in there and cannot drop out the shaft. Has anyone drilled this out in place and tapped it for 3/8? I really don't want to take the whole housing out plus I have to get the axles first. It's a stock rear end. Any advice will help. Thanks in advance.
