RE: Correct tool for this job?

I've got a broken stud, left side top (2nd from rearmost/flywheel end of case).

Cannot remove w/ vise grips - I used to own a "stud extracting tool".  It almost looks like a vanity pluming tool - goes around stud, you turn w/ rachet, and it tightens around stud as your turn to the left.....

Does anyone know what tool / where I might get this - I'll checked w/ NAPA today but I'm not optimistic........

thanks in advance for any suggestions.....

Have a good day!
