GTP-38 rounded bolt removal... :(

[AzPatMan]

So I picked up a turbo off 'the-bay'...
I wanted a cheap core to get familiar with it and rebuild it. Well, found out why it was so cheap.
It needed a rebuild, and Appears the previous owner knew this - because it looks like he may have attempted to pull it apart - and jacked it up.
The lower 5/16's bolts that hold the turbine housing were slightly rounded.
Other than trying to drill out and f'up the threads, any other ideas on getting these out?
I'm tempted to just get 2 inexpensive 5/16's sockets and use a little JB-Weld to stick them on to the bolts since there's enough teeth left to bond to.
Then just replace the bolts to the housing with new ones from a rebuild kit.

Any other ideas?

Sears sells a nice bolt extractor kit works great I have used it alot of stuff that was out there(people trying there own method which didn't work). Get that kit find one that goes on it easy go to the next size smaller beat it on with a BFH hit it with the impact and woolah bolts out

the bolt heads should all be a 12 point.
when used carefully, an air chisel does a good job of cracking a bolt loose.

I have that set and love it

I made my Samsung SGH-I997 send this.

If you get Really stuck,,, NOTHING beats welding! The Shock of the heat does wonders

So, if you can, you TIG a piece of rebar (bent in an L) to the top of what's left of the head and use it like a big allen wrench. If you can't, look for a friendly welding shop to help you out.

I'd try all the other stuff first though....

Yep,
I managed to get them out.
Seems my own socket was the partly the culprit. I used my 2nd set of tools that I normally use when I hunt through salvage yards for parts.
So I get home, and went through my Craftsman tools, and noticed I didn't have a 12pt 5/16's in 1/4in. drive - so I went to sears and picked up a couple new ones.
They fit like a glove, and managed to get those last two suckers off.
Tossed them and the old sockets into the trash shortly after!
Thanks for all the suggestions,
