Using ford alternator

[1932]

What pulley to replace one way on ford alternator? I have seen that people have used the ford alternator has any one had problems with it?
FFR said that it may over heat, but looking at it i think it will just send air the other way to cool.

I did not find a pulley for the new alternator, so i welded up the clutched pulley. Forgot to take pics.
