11 blade fan parts

[Martice]

Thanks Kdanie, i know the type4 breather box must be machined, forgot to mention.
To be honest here is what I plan to do if I find a 911 fan at a good price: Machine the fan ring, machine the case, build my own shroud from fiberglass.Hope it will work, I can't afford a kit...

I wish to do this mostly because i need the space in the engine compartiment for a plenum for a CIS system.
