Using the template pictured above, I fabricated a fixture that would align both the required 31/64 drill bit and M10x1,25 tap for the two offending starter holes. Using an insert for reference, I preset the depth of the drill bit with a 1/2" lock collar. Bolted the fixture to engine, drilled, tapped, and installed thread repair insert. Couldn't be happier with the outcome. Starter bolted up good as new.
