G40 alternator question

[Etches]

Doing a g40 conversion but using my alternator realised that the pulley has to accommodate both v belts. Just wondered if anyone had the part number for the pulley, as looking on etka now there is three 2 made by bosh and one by valeo. Has anyone got the one of a G spare or a whole alternator that they are willing to break or sell as a whole.

cheers
