Bonjour Yves,If you go to the Balmar web site at the following adress:http://www.balmar.net/PDF/Alternator-Regulator Guide.pdfGo to the bottom of page 3 of 8 in this PDF document, they list 2 companies offering pulleys for alternators.Bonne voile.

Double Pulleys

I have the same engine as you do, I put a 160 amp balmar on with a single belt and have had no trouble in 7 or 8 years of use.
