You will need to either find a wide-belt pulley that fits your alternator;
or else convert to a narrow belt. Many of the racer supply houses sell the
narrow belt conversion (BFE, TSi, Moss UK/TriumphTune, etc.), but they
aren't cheap.
When I did mine years ago, I had the original pulley bored out to fit the
alternator shaft. That's not an ideal solution tho, a smaller diameter
pulley would work better.
