Sorry, not sure on the belts, but what make are they? As if they are Roger clark lightweight pulleys for the crank, alternator and pas pump they don't require different belts.

Sorry can't help with that. Hopefully someone else here has the info. I take it you've asked them if they know who supplies them? I would have thought if they made them, they should know what belts fit, and where to buy them.

sounds like there not standard size pulleys, apparently there under driven same as GFB pulleys, so belt would be different size

i returned the pulleys and am now going to order lightened standard size ones.

Does anyone know if the crank and alternator pulleys are even worth changing? do they actually make that much difference.
Cheers
