My experience is that the fit will be about 4mm per side. Did this many years ago to better set up a touring bike's left side pedal "Q" factor and had to shave off about 4mm from the inside of the arm's face at the tapered hole to clear the LH cup. Otherwise it fit well and I rode the bike this way for thousands of miles (over a number of years, not on the one tour...). Andy.
