Help with broken 66 273 Dipstick Tube?

Oops, meant to re-post this

Use a slightly larger screw or "lag" bolt to screw into the broken tube.
Tighten until the broken tube turns, then twist and turn and pull with vice-grips.
I actually have a slide hammer and lag bolt specifically for that purpose, so I can leave the alternator in place.
Tap new one in using a 7/16 open/close wrench against the"flare".

Good luck

P.S. some use a 3/8? tap to try and thread the tube, but the tube usually turns before any significant thread is made .
Cheers
