Just called Christian Autos, he wants £120 which isn't bad for a new one to be fair, but still on the lookout if anyone has one kicking about locally.
 
100amp. 65amp ones are much cheaper, but all the ones I've seen have the external fan and a different pulley. Will a 65amp one fit if I swap the pulley over? I don't actually need a 100amp alternator in my Defender.
 
If the pulleys can be changed I'll give Christan Autos a ring and see how much he wants for a 65amp, that certainly gives me more options.

Just called them, he reckons it's not just the pulley that's different, he says the actual mounting bracket spacing is different.

Why not go and compare em alongside each other? It may be that you can pack a gap with spacer washers or fit a different size belt depending on what the differences actually are.

If you're thinking if fitting a winch or spots or heated screen in the future the 100amp may be the better option.
