Stripped out fuel pump mounting hole

I wonder if a stepped diameter stud could be found today ? Like 38 one end , 5/16 on the other.
No matter how you conquer this hardware problem, lets not let this happen again.
Disconnect neg' battery cable. Loosen pivot bolt upper alternator and remove the lower adjust bolt. Drop those belts and rotate the alternator as far clockwise as you can, being careful not to damage those wire connections. Better access and line of sight always helps.
Turn the engine by hand to a point where the least spring pressure reflects to the fuel pump.
You cant get alignment bolt to hole with tool such as 1/2 inch drive, or thick walled, or deep well, socket.
