Rather than replacing two pulleys from the Triumph to suit one pulley on the
alternator, maybe you could replace the pulley on the alternator. With the
old TR generator pulley maybe? Also, you'll have to be concerned with
alignment, and rather than changing water pump and crankshaft, it 's easier
to do that with the alternator brackets.
