Crankshaft Won't Rotate Manually
 

Here's my embarassing story:
Installing the crank - I did everything right when using the plastigage. During the final torquing I rushed, knowing I was on the clock with the gasket maker, and forgot to line up the nose bearing with the roll pin.
I first suspected something was off when a stud began to pull out (#11 in the sequence) on 2nd and final stage (37 ft/lbs). I left it and finished torquing. The crank wouldn't rotate at all.
So the bearing is out of round and the roll pin is crushed into the block. I took 2 spare nuts and bottomed them out on the stud and got the stud back in place, for now.
Need:
1. A front bearing without buying the whole set
2. A machine shop that will safely remove the pin. Should they be welding anything to the pin, or using a
3. The appropriate pin replacement. N10109001 works? It looks more like a solid dowel
4. To remove the problem stud and re-apply threadlocker?

Any help would be appreciated.
Thanks

Yikes!
