    I wouldn't mind trying that. Any chance of a part number?

    Vw heritage list 70amp alternators for type 4 engines. Explicitly states that it is replacement only for busses already fitted with 70amp units. The cooling requirements apparently greater, fan pulley required and ducting for cooling different. Fan pulley difficult to source. There must be some cooling concerns?

    Will dig around, I've got a new stator here somewhere. All my buses have the 75A upgrade.

    Vanessa's bus is getting the "70A" alternator as per what Paul77 mentioned above... Only difference is that alternator(Only on 2.0 Westfalia buses with factory petrol heater) is upgradeable to 120A. I have a fresh 120A alternator ready to go. The boot is different(round port instead of 'd' shaped port), the wiring loom is a bit different(Plugs and battery wires, more like Mk1 golf/Passat loom) and the pulley has a fan welded to it. :D

    No cooling concerns, just needed the fan on the outside as well as round rear air port.

    Hi Andrew, Did you ever manage to find the part number for that 75 amp stator?

    Cheers
