[alfa] Removing Broken Engine-to-Transmission Stud?

[Kevin Trent <trentkc@xxxxxxxxxxxxxx>]

I've got the transmission out of the '73 GTV as part of a prep project for 
winter driving, but the engine is still installed.

One of (several) repairs is to replace one of the four studs which mount in 
the engine block and extend through the transmission to hold the two units 
together.  This particular stud is the one above the clutch slave cylinder, 
and it is sheared off such that a) the break is not flat but angled; and b) 
there is no protrusion from the engine block, and the stud remains are 
slightly recessed.  Furthermore, the flywheel is still on the block which 
means the thin metal spacer between the block and trans is still in place 
and generally gets in the way.

I'm reluctant to start drilling out the remains of the stud, because the 
angled shear surface will slide the drill bit into the threaded side of the 
block, and muck it up.  Since the stud remains are slightly recessed and 
because the metal spacer is still in place (as well as the flywheel which 
limits working room), trying to weld a nut to the broken stud looks nearly 
impossible - it would be difficult with the engine out of the car.

I really do not want to remove the engine, though access would be a LOT 
easier.  Examination of a spare engine shows that the stud would be 
difficult to remove from the opposite (starter) side, though the welded nut 
technique might work.

Anyone been there and done this?  Any suggestions??  How about a source for 
replacement studs?
