alternator pulley question

[PeteG40]

I've got a quick question - i've got an alternator thats been used with a turbo convo (single vee pulley), i need to put a twin vee pulley on it (or toothies). 

As it had a vee pulley on it, there were loooads of washers etc. But what SHOULD it have on?

fan thing? then pulley then spring washer then nut?

From taking a standard G40 one apart last weekend:

Alternator
Fan Wheel
Spacer / washer (the big one with a keyway provision)
Pulley
Spring washer
Nut

Mine didn't have a key in the keyway (non G40 ones usually don't either)
