YOu have the right idea Rae...
A tap & dye set is a garage must. I used the shit out of mine this winter during the build. Even if it was just cleaning out threads have the time the taps were a life safer.
It sucks but it happens sometimes... I had to drill one out a few weeks ago when I tried to tight this grade 8.8 chrome heat shielf bolt on the front pipe exhaust. The red loctite had the threads good, but the heat from the exhaust made the bolt too brittle to take the grunt needed to break loose a red loctited bolt.
SNAP!
Drilled it out and tapped it...
Takes some time but wasn't too bad by the end of the day.
