I have managed to cross-thread one of the lug-bolt holes. Yeah, I'm an idiot, what can I say? I realized my mistake the instant it happened, so it's probably less than a whole turn that's cross-threaded.
I'm not sure how easy it is (or even if it's possible)to approach the hole from the back and re-tap the thread but that would be my preference if it's doable. Any other options or advice please?
